I can happily second the praise for Murray Haday at ProEdge. He's a great guy and a pleasure to deal with.
The best selection currently seems to be TrueNorth. Quite impressive. I haven't had the pleasure yet, but the word is very positive.
Some people have good things to say about S & R. My experiences haven't been as positive, but if you can get them to agree to a fair price I'm sure they are good folks.
You shouldn't ignore dealing with custom makers directly and most of the Canadians [but not all]can be accessed through the CKG site.
We have so many great makers who are also great guys that you really should check them out. The variety is amazing. Greg Lightfoot, Wally Hayes, George Tichbourne, Brian Tighe, John Freeman, Peter Wile, Eric Elson, Jeff Diotte, Thomas Haslinger, Chrisoph Deringer, Bud Weston... and many more whom I could also mention. The list is huge.
For fixed blades particularly, customs are a real bargain IMHO.
And don't forget Normark [Eric] for superb sheaths.
We've got some great guys up here.
