I have a lot of consoles too, including multiple consoles of the same type; if I fry a board I have replacements, if I don't I can sell them.
The biggest pain the the proverbial is that it is a pain to get bulky consoles out of their boxes or storage and hook them up with the stack of wiring they need to your television. I am getting around this with a universal portable system to include (eventually) about a dozen systems or more. This makes it far easier to play systems quickly and on the move. Started to document it on the BenHeck forum, making a MKII version now, will make my own website over next weeks and up it for all to see; I will post a topic here when ready...
