[MENTION=252763]Flog00[/MENTION] - Jim has some really good advice. My wife is not a biker but loves to ride occasionally. The tandem has been a great experience for us. IMHO size and fit are key, everything else can be "fixed." Do talk to wrk101. Our Burley Duet came to us through him.
I don't know the year but it is about a 1994 vintage. It had a 6 speed Suntour Accushift in the rear with Indexed barcons. I have since "upgraded" to a 7 speed. It works very well for us. It is nearly stock, otherwise, including the 48 spoke wheels!
Keep in mind that you don't want to look for a frame dimension equal to your single. The captain needs to be able to straddle the TT and spread their legs out far enough to support the bike while the stoker rotates the cranks into position for the Captain to step into the pedal. You don't want to fight having you shins or calf's turn black and blue because the TT is too high!
Riding a tandem is significantly different in nearly every way.
Perhaps you could provide a description of the type of riding you expect to be doing and how often.
