Also, I'm debating whether or not I should sell off nearly all my pre-NES stuff. The only thing I'd probably keep is a boxed 2600 and a handful of games. It would free up a lot of space and since I never played the stuff, I know I wouldn't really miss anything, but the market is so bad for selling stuff right now, I'd probably get something like 1/2 what I would have a year or two ago.
I'd say keep it. If you still want to sell it by the time the crisis is over (and prices have returned back to normal), then sell it. But if you sell it in a hurry now, I can guarantee you'll be kicking yourself later.
