The A3000 will provoke certain compatbility probs with ole games, since it has an 030 and Kickstart 2.0. One thing I dont know is if normal Amiga modes work on a VGA monitor. if they work, be ready for blocky-o-rama, since there are no scanlines in VGA monitors
I'd take the two A500s, more bang for the buck. if yuo want to use more serious shiznit, and perhaps plan on expanding the Amiga, take the 3000.
In the case you skip the 3000, can you please sell it to me?
Let's fight for it Twistin! Here! *bocko* take that!
