about 100 nights at the cheapest campsite i know of that takes caravans

or about 17-20 nights at some of the more expensive ones

Two surf boards, you only need one and can fix it pretty cheaply for like 20 bucks, but having a lot of surfboards is nice

A nice OLED TV. I love watching movies.

Edit: Holy cow OLED is still very expensive. I've changed my mind: projector.

First hobby, writting. So, enough pens and paper to the end of my life, and more... But not enough notebooks, I can't have enough notebooks.

Second hobby, collecting bones and dead things. What could be expensive is a nice shelf for exposing, but 250€ max. Dissection kit, 30. A big bag of salt, 20. Some pins, 5. This specific washing powder, 15/20 OR hydrogene peroxyde, 20/30. Uncolored dishwashing liquid, 2. Toothbrush, 2. Shovel, 15. Box of gloves, 15. A bin and a lock, 70. Nylon met, 20. This really nice vegan taxidermy, 550.

Infinite library cards!

digital art: i guess... a new drawing tablet? maybe a laptop that's also a tablet with pen pressure and stuff. would be neat

gaming: upgrade my pc (add a dedicated gpu, new power supply, water cooling, etc) + better peripherals

3 cheap synths but only half a more expensive one.

Reasonable amount of average magic cards or just a few good ones.

Half a graphics card.

Some nice wood for woodworking, but not that much if decent quality.

A flight ticket.

3 festival tickets.

0.5kg of ketamine.

A lot of 3D printing filament.

2 Warhammer figures.

3 years of swimming pool subscription.

A thousand euros in airsoft will get you a high-quality gun or two, depending on what you're looking for and where you're getting it from. Generally, replica pistols and "standard" rifles tend to be cheaper than anything heavy or exotic.

And you'll probably have plenty of cash left over, for things like safety gear, special clothing, and gun-related accessories like slings and holsters.

The most expensive gun in my collection, a replica of the pistol from Kingsman, was €430. I spent about another 100 on spare magazines, shotgun shells, and a custom holster. My next-priciest gun cost less than half that, even after acquiring similar accessories

I haven't put any money into modifying any of my guns, since that's an entire other can of worms I don't feel like opening. Most guns will be perfectly playable out of the box, rarely needing more than heavier BBs or a hopup adjustment to be improved.

1/13th of an AMD Epyc 9755

About like 10 of the must have flashlights or a few good customs. Or one fourth of some really extreme ones.

Depends on the hobby because I have too many...

Photography - not much unless I buy used, which is what I usually do. So some funky old lenses and adapters to get on the body, which usually nets some fun results.

Data hoarding - a couple of hard drives. Which I should really do, I'm coming close to 5% free (which sounds like less than it is when you've got about 115tb, which is why I'm not rushing out).

Computer Vision / AI - more processing power! But I make work buy me that stuff so its fine.

General compute - about 5 more tiny/mini/micros at the usual price (plus the usual upgrades) to either ads to the cluster or make a new one! Or one or two of the newer little beasts that I will probably be waiting another year or two to pick up.

Bicycling - a good bike for getting around! My bike is about 15 years old now, it was new old stock because no one liked the color apparently - which made it about 1/2 the price of what it should have been. I've been replacing gear on it over the years, but I'm tempted to buy something new, honestly less for going fast and maybe more upright, like a hybrid. Which I can get an OK model at that price.

A mid range set of motorbike gear (dirt or road) or a very cheap registrable motorbike.

Alternatively a number of interesting secondhand cameras/lenses, the number ranging from one to many depending on what exactly. I'll admit I have actually spent near that much on two backs for my 1960s era Hasselblad so you don't even necessarily get a whole camera...

Imagine how much SALE steam games I can collect!
