$800 for a wheelset? With that budget you can afford a great wheelset.
Peter White - maybe costs more, but if you had a set of wheels for 15 years, you'll want something really good.
But why not your LBS? Don't know where you live, but buying local is always a good idea, unless there just isn't anyone around you that knows how to build a good wheelset.
