It looks like it might be a UV EPROM eraser like this if the light inside is a UV light.
The EPROMs I generally get from ebay or aliexpress. Their prices have gone up since the china tariffs hit, but can usually still be found for less than $1 a chip, especially if you buy in bulk. I do not have a particular seller that I buy from, just whatever is cheapest.
The 27c322 SNES Adapter boards can be purchased from mrTentacle on tindie. This guy is absolutely top notch, everything he sells is great. His products ship from Sweden, usually takes about 2 weeks to get to me in the US. He sells the 74HC257 chips as an add-on for the boards as well, but they can usually be found for cheaper if you're willing to look. A word of warning, the adapter boards have a steep learning curve. they have to be very thin in order to clear an official SNES cartridge, so they are fragile, and they require removing the plastic from the header pins to fit. I junked two of them before I was able to get one to work, but now I have the knack for it and haven't had further issues.
The GQ-4X is still considered the gold standard for repros, but I actually do not have one. I have a TL866PLUS, with this adapter. It is not fantastic but it gets the job done. One thing you will want to invest in if you give this another shot is a UV EPROM Eraser. A lot of the time the cheap junk from china still has data on the chip, causing it to appear faulty. A pass in the UV oven or two will remove that, and you'll be able to reflash the chip. This is also invaluable when you mess up, which I do frequently. That's why the chips have the quartz window in the front.
Hope this gives you a good launching point about where to start. Feel free to reach out if you ever have any questions. Having a big stash of donors means you can make a lot of mistakes and learn lots!
These days the wrong kind of light might cause your system to crash but in MY day you could erase the whole damn thing
