Depends on what you need it for but I have a ten year old FLIR i3 with 64x64 pixels. It’s fine but the feature I would really like is that newer modules have both a normal camera and a thermal camera and they overlay the color image and the thermal image. That makes dealing with the low thermal resolution WAY easier since you can actually see which thing is hot. If you have a bunch of similar shaped chips on a board and all you can see is some rectangle is hot, it takes a moment to figure out which one you’re looking at. (I do this by covering each chip with my finger and seeing when the image is occluded). So you don’t really need high resolution for most stuff if you have the color image overlay. I haven’t shopped for them in the last ten years before those types were common so I don’t have a specific part to recommend. The thing is they are a fun toy but sometimes I question whether I should have spent $1500 on mine. I would suggest going on the cheaper end, not chasing specs for no reason, and just get the value out of it without breaking the bank. They’re neat but for my use case I’ve never felt like I really needed to have it. If there’s something that’s $300 go for it.
