try ebay, i payed £30 for a palm v.
the guy bust the charger packing it so he gave 15 of that back! and i got a new charger for £1 also on ebay...so the whole lot cost me £16 and about 4 in postage!
generally the older ones are cheaper suck as the palm 100....as long as it has 2k of memory you are ok with rip software i belive
