Edit: okay so I don't want this to look like a list of the only makers I "trust". I have had nothing but great interactions with every maker on this site and I fully expect that trend to continue. The list of makers I wouldn't hesitate to buy from (if i had the cash!) is longer than the list of makers I have bought from and I think that speaks to the integrity of the guys here. So rather than give a list of makers I approve of I'm going to list the makers I've bought from and what in particular I liked about their work. I highly recommend the OP or anyone else to have a look at these guys' work and that of all of the other knife makers on this site.
Bacustomknives aka Bill Akers - uses some of the nicest damascus and most insane (

) handle scales I've ever seen. His fit and finish are excellent and his knives are probably the most comfortable I've ever held.
DPKnives - solid knives, excellent value for money and excellent to deal with
LucyCustomKnives (aka Overmountain Knife and Tool) - the small utility blade I bought from him has been one of my favourite cutters (it features on his website) and a great guy
DCLKnives - interesting and thoughtful designs, great handle ergonomics, very clean fit and finish and uses some interesting materials.
Marcin Bona - phenomenal fit and finish, awesome aesthetics and utilitarian designs. Also some of the most comfortable knives I've held
Matt Bailey - very nice fit and finish, great melding of materials and probably the sharpest knife I've bought. Also an absolutely great guy.
Austin Goldman - solid quality materials and an industry standard (Bos) heat treat at a very good price.
M.Presnell - solid work, utilitarian and thoughtful design and excellent value for money
Jason Wilder - I have one of his neckers and it's my current favourite knife. The ergos are great and the fit and finish is pretty much flawless. An absolute pleasure to use.
Dan Graves - Dan's pattern welded steel is really nice, very clean grinds, great matching with the handles, a real gentleman to deal with and unbelievable value
Bama - very clean grinds, incorporates stag handle scales very nicely, comfortable and good ergonomics.
G L Drew - comfortable, great looking, great grinds and rock solid. Everything you could ask for in a knife at any price, and a great guy to deal with.
I'm also eagerly awaiting a package from Kelley from HardEdgeKnives.
...and I know I'm forgetting someone
I've inconsistently used screen names or actual names but you will find them easily enough if you want.
There are certainly differences in quality, price and style but I think each of them makes a product worth at least as much they charge.
Enjoy
