Well, sometimes you just have to gamble. If you get a super deal on a board that you can move and not lose on, grab it.

Conservatives will wait forever and be stuck with the old model - IMO, life's too short for that.

I've bought, sold, traded and kept many boards, sight unseen. A may have lost a few bucks, but nothing major.

Not recommended for a person on their last dollar, but 'cmon, this is pocket change.
