Hey raistlin65, you should be able to get the ESEE 3, handles, and sheath for around $125 with free shipping from TKC. They sell blade "blanks" (knife no handles) for under $50, plus $50 for the handles, and $25 for the sheath. You have to make sure you choose the "blank" blade not the knife with the ESEE factory handles include. I just did a build like this for an ESEE 4 a couple months back.
For the JK suggestions take a serious look at his
http://www.bladeforums.com/forums/showthread.php/1224594-Element-O1-Models . Look at the model with the 4" handle.
I am 6'4" and about 280 lbs. (was 357lbs at my peak). I wear XXL gloves, and have busted a few pairs. Standard XXL gloves are for hands with 10" circumference, mine are 11". The ESEE fits very comfortably and the handle measures a hair over 4" from guard to pommel. For me 4" and up is ideal for full size knife handles.
Hopefully that helps.
