This list was compiled earlier in the summer:

The cheaper ones (but still good quality are): Kabor heavy bowie and Ontario marine raider bowie. Becker bk9 is somewhat higher price category. RTAKII, RD-9 and Crowell/Barker Competition knife are up next in price. Any one of the knives would be a good purchase I think.
For production blades in the 'chopper' category, I think the Becker bk9 provides the best price/value point. The kabor heavy bowie is good quality but kind of a beast while the BK9 has great F&F. Going to the next price category, again the RD-9 is a brute, survive anything knife while the Crowell/Browning is a bit more refined. Both the latter knives justify their cost via providing higher end mircata handles.
However, in the end, I agree with Okoban and others. A 9-10" knife really isn't a very versatile knife unless what you like to do is whack at wood. Carrying a 9-10" knife almost guarantees that you will have to carry a smaller accessory knife (oh the BK9 comes with one) and the reality is you will find that the big chopper spends a lot of time sitting on top of the picnic table until it comes time for fire prep.
A 6" to 7" knife is far more versatile as a camp knife on its own IMO. The RC-6 or Breeden Peacemaker would make excellent camp knife (I own and use both for that purpose routinely). Of these two,the RC-6 is quite a bit bigger because of its 1.5" width (blade width makes almost as much difference in perception of knife size as length). The breeden is more comfy on the belt and lighter in application - it is a 6" knife the feels and operates like a smaller blade but has the extra length to do batoning etc. The peacemaker makes a great camp knife for those who like a lighter on the run knife. The RC-6 feels like a bigger knife than its 6" suggest and is capable of more chopping than the peacemaker at the sacrifice of finer control.
Finally, I'll echo talking to a few of the custom makers around these parts. First you can ask them their opinions and come up with something that is new and unique to your specifications. Bryan Breeden and John (JK-knives) are very open to implementing a client-initiated design. Also Koyote has been cranking out a bunch of wonderful big blades as of lately. Mneedham mentioned Landar - who had a beautiful bowie up for sale not too long ago either.
