Wanted - 18" rear wheel, spoke or mag (or both!)

[bcXS400-81]

I'm looking for 18" rear wheels for both my bikes. Haven't decided if I'm going to run spokes or mags on the first rebuild, so whichever I can find an 18" in first will probably be the ones I use. I would prefer a drum mag rear, but disk will be fine too. I suspect shipping on these things will be killer so obviously the closer to my location (BC, Canada) the better! Thanks.
