Yea I have been torn. The KK road machine is cheaper than the fluid 2. BUT the fluid 2 is available via performance, so with my team performance plus a sale it might be a little cheaper.
THe KK is power calibrated and has a pretty cheap addon to give you power during your workout. That could be cool.
Or get a performance brand fluid trainer for $130. But I would rather buy a good one once, than buy a cheap one and upgrade later.
