About average, I mainly wanted to purchase from a local shop though to support business. It’s a common date night spot for my gf an I bc they have a small collection of cabinets and pinball machines to play at the shop too.
We are long past the days of getting them for near nothing so at least supporting a local shop is good. Still crazy these go for so much now, but still cheaper than when they were new!
$80 is definitely a high price. If you buy a GBC from eBay or Craigslists etc on any given day I’d expect to pay around $80.
However, if you’re monitoring market places like Facebook or Reddit, you’ll come across them for like $30-40 by people who just want to get rid of them. It might take a few days of waiting to come across one but it happens regularly you just have to be quick and have multiple payment options ready.
I’ve bought a few GB-GBAs recently and I’ve never paid more than $45 for one. I probably average $30 or $35 because I buy multiples.
Grab a Flash Cart so you don't have to pay outrageous used game prices, and find some kind of high capacity battery mod because I use a flash cart on my GBA and it drains quick even with replacement battery.
Oh, and definitely make sure the battery contacts aren't corroded/had leaky batteries, though if you're gonna swap it for a rechargeable one, it may not matter?
Sorry, but I fail to understand why you would not just buy a RG35xx of something similar? The purple transparent RG35xx looks so much like this GBC. But with a much better display, battery, you can play everything from NES to PSX on it, etc.. Not to mention that is much cheaper!
I like retro gaming, but I guess I'm not a purist like some. I prefer to play my retro games with the luxury of savestates and a better display.
