I wish I hadn't been little with no disposable income in the 80's... so I could stock up on G1s! But that would also mean that I'd be like 50-60 now. D: So maybe not!
G2s would've been great. Though I was a raging teeniebopper back then and I purposefully avoided the toy aisle and spent all my extra money on clothes and accessories. So I didn't even know they existed until I started collecting last year. o_o
I also wish I would've bought a few G3s while they were around. I know they're easy to come by now, and cheap MIB, but I hate opening anything MIB when it's not produced anymore. But since MIB G3s are so cheap, I really only want to buy those and get them loose in thrift stores. ARRG first world problems. lol
