This is what I recommend!!!
Get a cheap Amiga 2000 computer with C=1084S monitor, a nice big HD and maybe a 030 card with 8Mb or more RAM. Then buy boxed original games of popular titles, get the Whdload version installed on the HD and you are set!! You could also display the box next to the Amigas or on the wall, etc!!!!
You'll need KS 2.x or 3.1 of course but that's easy.
