If you can live with only 4 10G ports, those types of switches are far cheaper than 16 port ones, I've gotten them for ~$100AU off eBay auctions before.

And if you're fine with spending a bit more you could get a 8 port ubiquiti aggregation switch, and then upgrade to a bigger switch once the price comes down.

Mikrotik stuff is pretty good and quite inexpensive. They all run RouterOS, which is their linux distro for switches/routers. Fully managed and can do basically anything L2 or L3 you could want. Worth noting that availability and pricing has been pretty variable from their resllers for a while, and you will pay a premium via Amazon. Here's a list of relevant product product pages with the port counts and MSRPs:

• A router with 12x SFP+ and 2x SFP-28/25g for $600, I run one of these as my router.
• A switch with 16x SFP+ for $500 Probably the right switch for you
• A switch with 24x SFP+ and 2xQSFP/40g for $600 I run one of these as my core switch

Also these may help for some corner cases or change your ideas on what you want to build:

• A tiny switch with 4x SFP+ for $150, I have a few of these where I want multiple things plugged in to 10g, but don't want to run a cable for each of them as the devices aren't usually using a full 10g at the same time.
• A switch with 8x SFP-28/25g and 2x QSFP-28/100g for $1000, interesting because each QSFP-28 can be broken out into 4x SFP-28, so a total of 16 25g ports. Just imagine making the jump to 25g instead of 10g, wouldn't it be glorious?
• A switch with 48x 1GBASE-T, 4x SFP+, and 2x QSFP+ for $600 Who needs anything else? Break-out the QSFPs into 8 SFP+ ports, you've got 4 SFP+ ports natively, and then another 48 ports of 1g copper. Could be pretty interesting. There is also a variant with PoE output for $400 more in case you need to run cameras/APs/whatever and don't want to run injectors.
• A super weird 2x SFP-28/25g network card that is actually a full router for $200 I haven't figured out a use for these yet, but I kinda want one. Otherwise my SFP-28 ports are being wasted at just 10g, right?
• A switch with 16x SFP-28/25g and 2x QSFP-28/100g for $1600 Total overkill, but I just had to list it since it falls in the middle of the price range you were considering but is so much beefier than the Netgear offering.

If you wanna dip your toe in the 10Gbps water, I recommend you giving Mikrotik a look, specially CRS305-1G-4S+IN or CRS309-1G-8S+IN. The former has one 1Gbps RJ45 port plus four 10Gbps SFP+ cages while the latter has 8 10Gbps SFP+ cages.

Check out the FS stuff. It's pretty cheap brand new

They SFPs are cheap and work very well too.

The Brocade ICX switches are very affordable for the performance. Great way to get a mix of 1G PoE, 10G, and 40G for under $200. Sadly they do consume a fair bit of power and most are loud out of the box. Although, there is a fan mod you can do to make them run quiet and cool.
