@zenimus, and everyone here really, the Polymega appears to want to be the first to really do this well. I'm sure a lot on this forum are pretty excited for it.
To the OP, I do worry about this. I try to use wear dispersion on my machines. It's easy with Nintendo because of backwards compatibility: Gamecube on Wii, Wii on Wii U. This way I'm not putting too much stress on any one console and in some cases improving the fidelity. I'm getting a Wii U soon, as I worry a good bit about my launch Wii breaking down. So for PS2, for example, you might consider picking up one or more PS2 slims on the cheap and rotating them occasionally. You could get multiple versions to justify adding them to your collection (color variations, slim, phat, special editions) and rotate them.
But, as others have said, spare parts and a bit of elbow grease (and some basic soldering skills) will get you pretty far in this hobby.
