I am big on the bike trainers. Do you each have your own bikes? If so, getting a trainer, or two if you want to ride together, would be an alternative solution. Here is a link to one on Amazon. You can certainly find them for less, but this shows the trainer and what it looks like with a bike on it. http://www.amazon.com/CycleOps-Fluid-Indoor-Bicycle-Trainer/dp/B000BT7HWY
I have this, have had it for several years, ridden many, many miles on it, and never had a problem. Well worth the money. To me, it is more comfortable than a spinning bike.
