I'm strongly considering some everdrive options myself including the upcoming GBA version. Even when Samson had hit $400 like 3-4 years ago that was too much for me to tolerate so I wrote it off. The most I technically put out was about that much for Bonk but it was all tradebait, no cash involved and even that still sickens me I did it and I like that game a lot. I'd love to have a real copy of Samson and Panic Restaurant but the price has jumped the shark too much to justify the price when I'm on a tight budget. I've been pushing off my game collection over the last many months to get up to around the 2K mark for a gaming level do it yourself laptop that'll last me for years so to think I'd put almost half that into Samson is straight up retarded. More and more NES and SNES games are jumping into that over $100, closing into the $500-1000 level stuff now that's total insane collector pricing, not something for someone who is sane or on a budget. If you just want to play it, get lucky, trade some junk, or get a flash cart, or get someone to make a nice *ahem* 'repro' that fits with the collection.
Another option I'm considering for those 2 games are either Famicom releases or buying the infiniteneslives writer and boards and making my own Samson and others and using an excellent printer to make a solid copy label so it fits with things. I'm not entirely set on going into a flash kit again, I tend to get adhd with those things and nothing gets played or finished.
