Hi Geoff,
i recommend SWC. Steve (the S of SWC) is a top fella who produces some smashing work. If budget is a concern, try his knife kits. I just recieved mine from him and all i can say is FANTASTIC. He's very flexible with the spec's of the blade. His standard ones are 11cm blade from 4mm 01 stock but i asked for a 9cm blade in 3mm stock which is what i got. I didn't want the pins and scales so he knocked £10 off the price, but i got a RM style sheath and the total was £101 inc recorded delivery. A bargain price for a high quality, highly personlized (i am fitting my own scales) bushcraft knife to your own spec's. Highly recommended! Here's the link,

The Gene Ingram knives seem highly recommended and looking at other members knives, i can see why

Dave Barker knives are very nice, maybe a little out of your price range, but deffinately worth a look,

Bison Bushcraft are again a little expensive, but you get what you pay for, even though there is a waiting list,

Always try to look at the 'Makers Market' part of the forum, there have been some belters on there recently and Rapidboy put a link up in 'Members Classifieds' the other day, to BB and some blades for sale by Shinken and Mick Spain at very resonable prices.
Having said all that, British Red, Rapid Boy and a whole host of otehr members seem to be 'Sharp's Officionado's' (sounds like a title for a Sean Bean programme) and their wealth of experience and expertise may put me back in my pram!
Good luck and let us know how you get on.
