Been looking too at craigslist for Revive. Bet 200 and $300 is fair for a good clean bike. If you want to change parts easily, look at the derailleur version. Internal multi speed hubs are expensive and hard to service. THe Revive design is a good city commuter or shopping bike. If I were to get one, I would install a wide range cassette in the back like an 11 42. Purchased Chinese branded 1x parts group from ALiexpress and they work really well.
Craigslist is a good source for recumbents. Just got a Rans stratus XL in fair condition for $300. Some minor cleanup and tuning and it is good to go.
