Bought a Terratrike Tour last March with the 26" rear wheel, it wasn't cheap for me, but it was the chance of a lifetime to get one, so I was willing to sacrifice other things. Absolutely love riding it. Even on those days I'm not feeling too great, where riding a DF bike would be a bad idea, this keeps me going! also helps me keep my sanity, getting out and moving, fresh air... even if I have to go only 3-5 mph at times.
