Hrm...
I like having a good bit of belly (width at the front of the blade) and for this reason, I find most clip points don't work for me. Out by tip, I think, "Where's the blade?"
There are 2 clips that I like. The Opinel and the Buck 112.

The Opinel pictured here is the #8. The #7 (and 6) is smaller and may be more your preference for pocket carry. The #8 is just fine for *MY* pockets. They are also available in stainless.
The 112 is too thick and heavy for pocket carry. The Ecolite 112 work for pocket carry as it uses lighter scales and looses the brass bolsters. Sort of like Buck's answer to a locking sodbuster with a clip point blade.
Also, the GEC 72 has a mild clip, but that will go past your $50 budget.
