The Busse knives are good looking designs. However, I'm always a little skeptical of any knive dubbed a "combat" knife. Unless you're a soldier who might actually wind up in a hand-to-hand situation, the last thing you want on your person is a self-labelled combat knife. A good lawyer would eat you alive by that fact alone if you ever, God forbid, had to use it for combat.
And really, the last place you want to find yourself is in a knife fight. Everybody is going to get cut, and everyone will come out a loser to some degree. Faced with a knife, I'm going to do one of two things. First, put some distance between me and the knife wielder. If that isn't possible, or if my wife is with me, I will present said offender with the business end of a 9mm. Only idiots bring a knife to a gunfight.
That said, my pick for an all-around, affordable (note that I said affordable) fixed blade with good steel would be the Cold Steel Master Hunter in Carbon V. If you're going to be around a lot of water, it also comes in AUS8 (stainless) steel. For $47 (try this link
http://www.wholesalehunter.com/product/coldstee/colddes/masterhunter.htm ), it is a heckuva lot of knife for the money. Comes with a great kydex sheath, and it can handle about anything you want to dish out.
The Carbon V, though it requires more maintenance, gets sharper than any steel I currently own (which includes 154CM, ATS34, VG-10 among others). VG-10, which the Fallknivens feature, gives it a run for its money, but the Fallknivens are around $50 more new.
For the money, you can't beat the Cold Steel. If you want to spend more, you can beat it, but not by a whole lot.
