Of the three options given I wouldick the SRK with the Kabar being a close second.
Other suggestions would be a Spyderco Street Bowie which is designed with martial blade craft in mind. It's a bit smaller and not quite as robust as something like the SRK, but it is a much better slicer, is very secure and comfortable in hand, and carries very easily due to it's extremely light weight. It can be had for around $85-90 if you shop around a bit.
If you want something heavier and more robust take a look at the BlackJack Tac Ops series. 1095 steel, micarta scales, and kydex sheaths for $115-150 shipped depending on which knife and which options you pick. They have some tactical flair, but will also function as solid camp knives so they can save you some cash by being good all-rounders.
Another possibility is the Condor Toloza. More affordable than the other options, it should only run you about $60. The sheath is leather rather than kydex or FRN, but it's a very nice inexpensive option.
Others have already mentioned Beckers, but it's worth repeating as they are a great option.
