In 2008, I started buying up old kit to relive my youthful Amiga days. PPC card, A1200, BVision, ethernet, etc. While I enjoyed it overall, I found it to be a hideously cobbled together mess in the long haul.
After that I got a SAM 440ep, and I use that for the new gen stuff.
For the old stuff that isn't 100% friendly with the PPC rig, I've got both an Amithlon and a WinUAE rig that work just super.
I was originally one of these guys that wanted the A1200 for nostalgia sake, you know that nice old school keyboard feeling, etc. I got over that pretty quick, to be honest. Nice mechanical keyboard and modern mouse on the Amithlon/UAE rigs, best "Amiga" I've ever owned.
That being said, I still fully understand the hardware purists out there. I simply realized I no longer have the patience I had 20 years ago to fiddle around with cantankerous old hardware and finding parts on ebay to keep them running.
