I've bought mine in perfect condition for ~140$ (few months ago) and I would definitely do it again now. Judging by current state oh such devices (non-existant)market, I would probably do the same even +1 or +2 years from now

don't worry about operating system. Maemo is all You need (it's based on Debian), with chrooting to Easy Debian, if You need really specific things (well, running full fledged GIMP or Open Office on You "phone" isn't a small feat). Meego is rather for developers now, and Nitroid for people that need some Android applications. To be honest, I *never* felt any need fro Androids "apps" - You got everything for Maemo, and it's much better than any Android adware crap You may find. There is nothing for Android, that we can't have ported to Maemo.
