I have a line on a Rans Stratus LE with a 1-year-old new-model seat. The Stratus is a 2005 or 2006 model. Mileage around 1000 I would guess. Seller wants $600. Is this a good price? I have searched around on the web, but I am new to the whole used bike thing, let alone recumbent models. I asked the seller if he was firm on the price. He said make an offer.
