Interesting thread. It depends in how much money do you have in your pocket and how much do you desire to buy retro hardware. I've spent enough money to have around 4 PS3... but I have none. Actually I'm playing newest games in my mini ITX inside my old C=64. You can postpose buyings as long as you enjoy what you already have.
I have a lot of things to do in my A1200, as to install a new PSU from Amigakit in it's box, unopened since a month or so, but I will keep in my new PC (C64) only, for a time, as I'm enjoying it A LOT
