I've got to go with Esav on this one. When I think it might get ugly, my original Microtech Socom Elite gets the duty call for a couple reasons. The First reason is that it's taken all the unkind things I've ever done with it in stride. The second reason is that because I've used it hard for a couple years now, it has some "personality" marks so I don't feel guilty using it hard. I'm sure my Amphibian would probably work just as well, and perhaps pry even better because of the greater support behind the tip.
Unfortunately, as was mentioned in another thread recently M/A Microtechs are getting harder to come by, although last I looked, there was a Socom Elite in the exchange forum in your price range...
I'd also nominate a couple Al Mar knives. The SERE 2000 gets great reviews from everyone and while I don't own one of those, I do have a Shrike and it seems like it's just as tough as the SERE 2000, just pointier! Of courst the extra pointiness of the blade would make it more prone to tip breakage if you pried with it a lot, but so far it's held up really well for me. These can both be had well under your price ceiling, perhaps even under $100.00 used in the exchange.
Of course there's always the Benchmade 710, although I personally don't care for the handle designs.It does seem to have a loyal following and a reputation for toughness.
I'm another one who doesn't like the Strider folder designs, Buck or otherwise. While I'm sure they're as tough as crowbars, they have about the same appeal to me. Different strokes for different folks I guess.
Before the Strider flames begin, remember that these are just my opinions, yours may well differ.
