Duplicolor with Kevlar is a little more, but short bed I used 3 coats, gallon of the stuff was around $100 and still have some left. They also ha spray cans for touchup and areas not easily reached. I used the small roller at first but ended up with a 3" brush. Prep is the key, 180-200 grit was perfect and many have asked where I had it done. The roller just takes too long and is a bit inconsistent in coverage. YOU HAVE TO STIR IT...A LOT to get it all mixed well. Water cleanup when wet, grinder when dry. Very hard on knees when done and set and a semi-rough surface = no sliding of stuff in the bed (but tie it down anyway). Plan on several hrs and you can recoat anytime after a 1 hr wait. Go easy on the first coat, you will still through it to the bed paint but the following coats lay on thicker and build nicely. You won't be sorry and will save at least 400 bucks!
