You should definitely buy RE(1) for the gamecube. its an amazing game. As stated above the controls can be a bit awkward but that what makes the tension so brilliant. I can't decide whether 1 or 4 is the better game overall because 1 is a lot more scary. The gameplay in 4 is way better (the Wii version is incredible).
You can buy REmake for under $/€ 20,- and thats definitely worth it. Also considered the replay value. You have to beat the game with 2 different main characters to get the complete game.
If you like RE than I would suggest to bu Zero as well.
Personally I cannot really enjoy 2, 3 and Code Veronica anymore, because of the graphics, but when I originally played them they were really good as well.
