what's cheap? I have a rear but it's not exactly cheap as all alloy and large flange hub - nice.
If you're in Greater Manc I spotted these (inc's freewheel but steel rims though)http://www.gumtree.com/p/for-sale/rigid ... 1033172459
Otherwise seen a few on eBay, new or NOS (Quando on Rigida or Weinmann IIRC)
