You can read a review of the trike on Bentrider back in the day when it was introduced
'BentRider Online » Actionbent Main complaint was the hardshell seat (vs mesh). That would be a definite deal breaker where I live. I couldn't stand riding in a pool of sweat which would be the case in the desert heat.
If you do a wide area search on CL, two show up. One on the Boise CL for $500 and the other in Grand Rapids for $750. It is really hard to get anything that isn't entry level (read cheap components, heavy, and often with inadequate gear ranges) in this price range. Several of the entry level trikes on eBay are above these prices.
You can see the components on each model here:
