If you shop about you can get the original Sidi vertebrae's for around £80. Very good boot. My mate got a pair of these (the race ones) and they seem OK.
If they're anywhere near size 10, I've got an old pair of Styl Martin boots, in reasonable nick except that the left hand toe slider is missing (not that you would need it ).
I still wear them from time to time, cos they're completely waterproof, warm and very comfy. But they're a spare pair and I don't really need them.
If they'll fit you, they're yours for a brekkie and a couple of pints.
Bought a couple of pairs of Frank Thomas boots at the last BMF show, think they were about £30 each, got one of the waterproof type (aqua) and one ordinary leather. May not be the "in" thing to wear but they are very good value for money IMHO.
I'm not a huge fan but Hein Gericke do some good boots at reasonable prices, I tend to have a wander down at lunchtimes for a nosey around cos its the only bike shop in walking distance and the boots are pretty good in there.
