Found this Raleigh tandem for sale in my area yesterday. Seller says it has low miles and has a 26" frame. Asking price is $350. I haven't been out to see it yet but it looks sort of smallish to me to have a 26" frame. I've emailed them for more info. Any ideas on model or age of this tandem?

I assume they should be saying 26" rims and not frame. I don't believe there is a stock 26" tandem frame, and for that price, the bike is very likely stock ;).

Really good advice about pricing and buying a used tandem can be found at The Tandem Link (http://www.thetandemlink.com/LearningCenter.html).
