Thanks for all your responses!
I did email the worksman folks about the folding tandem. The thing is 70 lbs and doesn't actually get that small when folded. Plus there is no way to actually ride the thing before a purchase, and to return it requires that you pay shipping plus a 15% restock fee. Ack! combined with the takes on it here and on the tandem thread, its something I won't do.
So... bidding on the Montague on ebay and saving up some money for the BF seem like the only options.
My boyfriend and I are waiting for the first warm day to rent a tandem and try out our "team." He thinks I'm nuts, by the way, but I'm tired of his complaining how slow I am when we cycle together.
OK, as an aside, anyone here try out the cyclemorph? cyclemorph.com I wonder if this is an option for us?
