I own both the BK-2 and the ESEE 5. The grind is different enough to make a difference in what you plan to do with it, ESEE is thicker. For the money, the BK-2 is a great knife. Add micarta scales, and a kydex sheath, and you have as nice of a package as the ESEE 5.
Add a lanyard to either, and they will chop way better than you might think.
For camping, bushcraft get the BK-2 if you need to survive a plane crash get the ESEE 5.
There's lots of great value in knives for $80. There's a guy, goes by Kentucky, he forges 1/4" thick ,4" long blades of 5160, and sells them here. His last one was $85. Totally worth checking out.

IMHO, a forged knife will outperform many production knives, ala Ontario. Forging 5160 brings out it's best qualities, where Ontario just does a heat treat.
I have a forged blade that holds an edge and will not chip or roll after an hour of chopping hard woods, it's 5160. My Ontario RD4 chipped pretty badly going through an old golf ball, and it won't hold a good edge.
