I just spend $575 for it - it's laced into an old Zipp 404 tubular. I don't want to run tubular for training which is what I want the powertap for so I will be yanking the rim and either selling it or lacing it for TT's.
Not sure I want to invest another $200 on it just yet. Getting close to the cost of a new one for me at that point. I might just use it as is and see what I think. If it's not going to hack it at least I will have a better idea of what I want.
I decided to get it because I looked at the prices on the new line on saris's site...

Anyone know if I can use an alternate HR strap? One of the one's I have already?
