Thanks, Rich - that's good advice that I probably won't take

A new wheelset will be portable to whatever bike I get next, and for the winter, all I need is something reasonably solid that I don't mind feeding to the road salt - and this Kmart Special will fit the bill nicely, at least on those (hopefully few) days where conditions are such that I can't take my road bike!
