I have two slipjoints I got for ~200. I have a gary crowder two blade trapper, with jigged bone handles. It's a great design, good execution, but had a few problems with the grind (still sharp as a razor) and slightly loose blades. It was worth the price, it's a user, and I bought it off his table with my eyes wide open. However, if I was more anal retentive or looking for a safe queen and bought it over the internet, I might not be so happy.
I have a henry parker single blade of his own design. I bought it because the execution was flawless, the pearl was pretty, and I always wanted a pearl handled knife. From another maker, the pearl alone would have been about half the purchase price. I didn't love the handle design, until I started using it. Now, it's my little gem. I sure hope he hasn't quit.
Note that for $200, crowder gives bone, ATS34, fileworked liners, nickel steel bolsters/liners and two blades with good execution. Parker gives ATS34, steel liners/bolsters, single blade, filework, pearl handles and great execution. For $200, that's considerably cheaper than the Case Bose knives (made by Queen?) that run $300 or more.
Both makers can do a great nail nick, something that some higher priced or newer makers sometimes can't seem to get right. A slipjoint with a poor nail nick is a sad thing to own. I reject them out of hand.
Edited to add: When you start shopping for entry level customs, the best place is at a knife show so you can see and handle them. Beware there is some real garbage out there, even by makers whose pretty knives you see in Blade or KnifeWorld in their photo spreads. If you buy sight unseen, don't buy w/o the right to return with a money back guarentee, unless you can afford to put a few hundred down a rat hole.
