Best place to buy.

OK - this is going to seem a little strange, but hang with me and I am sure you will see my logic (who are we kidding, nobody sees my logic).

I am looking for a place to buy an inexpensive rear wheel with a campy hub.  Weight is not an issue, looks are not an issue, aerodynamics are not an issue.  I need a wheel to mount a trainer tire on for this winter (as my maintenance program has a lot of trainer time on it and I don't want to burn up my regular tires.  I also want to be able to just switch out wheels instead of re-mounting the tire anytime I would take it outside (if it gets warm for a week or we go south).  This wheel will never go outside and never be ridden anywhere but on a trainer, so none of the normal "issues" are important to me.  It needs to have a smooth hub and it needs to be true - that's pretty much it.  If it already has a cassette mounted it would need to be a Campy 9 sp, but I have an extra cassette, so I don't even need that. 

Here is the question - where do I find such an item at a bargain price?  What kind of wheels come on your lower end bikes that I could try and locate (like Alex Rims).  I have looked on eBay for about a month and I have looked on craigslist, to no avail.  A used wheel would be fine with me.  Anyone have any ideas of where to get such a thing?
