I'm kind of surprised to see the prices as high as they are. It's been a while since I purchased one, but it seems like they were cheaper then. Seems like a good one was around $2500. Now I'm seeing them anywhere from $3-5k, with lots of miles. I think we settled on one off of ebay. Complete with a transmission and a warranty that starts after the swap is done, not the day I buy it. It's not the cheapest, but we feel it's a good compromise between price and miles. Price is under $5k.
Still if one pops up here in the next day or so, I'd like to at least talk about it.
