Budget 27" rear wheel - where to buy?

as the title says really,
this is my first attempt at converting to fixed wheel from an old racing bike i found on freecycle..
it has 27inch wheels, so i'd much rather keep to that size than decrease to 700c,
only recently i realised it wasnt just a case of,
remove the freewheel, screw on a cog.
rather i'd need a hub designed for fixed wheel bikes, with two opposite threads etc..
im looking for the most basic wheel going tbh, i thought buying a complete would be cheaper rather than pay to get crappy hub+rim built...

thanks in advance

dunno i'm in the states, but follow through with this and don't do a "suicide" fixed. some ninny gonna come here and say go ahead with it. don't.

if you can't find, then go 700c.

Am I right in thinking that there is only abut 4mm difference in the diameters of a 700c wheel and a 27" wheel? Or am I wrong? I could be. If not, are the massive clearance issues with old frames a change in taste and aesthetics of frame geometery, or did they use deeper tyres?

haha, okay i'll keep that in mind,
i think i briefly came across suicide fixed on a "how to convert to fixed gear" site lol

700c are so much more common, i don't think i'd have much trouble finding a pair of those :/ but 27"... -.-

i think it's 8mm? the rim/tire sizing and all the interchangeable terms used is something i've still yet to understand properly,
i would prefer as much clearance from the ground as possible for safety when turn etc, but it may be a case of me worrying too much about the difference between 700c/27" and eventually just getting a 700c pair

me and edscoble were chatting about this:
apparently a 32c tyre on a 700c will give nice clearances.

I've been thinking along the same lines, and who would beg to differ from Ed!

I'm going for 700c x 38c cross tyre on a new bike, going to double check 1st....
