powertaps are pretty good.
new ones are £700 - with waranty
Open Pro hubs are the usual build - pretty indestructible
if it still works, and its cheap then go for it. If its pricey - then you have no warranty etc etc
I have been looking on ebay but refuse to go above £300 for a second hand wheel with no warranty. (I've had to send my quark back once - second one has been brilliant)
next purchase is the joe friel book on power - nice intro book. The coogan book (training and racing with a power meter) is more comprehensive but a lot heavier....
Also 'goldencheetah' is a free open source desktop app for power analysis. use it along side training peaks.
spend a month just looking at the values, then do some tests, (1M, 5M 20Min max efforts) to work out your cp60 - ie what you can maintain for 60 mins. all the power zones work off this......
