Tirerack carries 15 and 16" in type H. The 16's are $119 each, 15's are $89, 17's would probably be around $150 each new. (just a guess)
I love mine, SO easy to clean! I like the plain 5 spoke design, don't forget hubcentric rings if you get them.
If the ones you're looking at on ebay are in Skillman, NJ, they are type E. Looks like a good deal with the tires, wheels appear to be in decent shape.
