I have a Revive and were I to sell I'd likely ask the same as I paid, around $325. While the OP makes a good point about parts, this is a comfortable ride that looks nice and seems to hold its value. There are two on Ebay now for $350 each and that is the price I most often see although I've seen them listed from $250-$700.

If I were the OP I'd spend a day test riding various bikes including the Revive and others, and that might provide enough to make a more informed choice. If it is nothing special, don't pay a lot. If the comfort is detectably more than other rides, consider that.
