What’s a decent blade for ripping accurately? I’m using an old Craftsman 113 belt-driven saw, which I understand isn’t very powerful. I’d like to get nice rips on some 3/4” thick oak. If I can rip thicker stock in the future, that would be great, but as long as I can at least rip thicker softwoods too I think I’ll be satisfied.

I don’t expect to do enough woodworking to worry about a blade made to last through many re-sharpenings; I just want nice rips. Is a $20-30 Diablo from a big box store going to do what I want, or do I really need to step up to the $70-80 range for cut quality? Thanks!
