another option when applicable, is the Porta-Band, as long as you can get the band where its needed, not really much can beat it, if anything at all... a few years back i had to cut 100+ pin piles that were about 1/4 inch thick, by 3 1/2 inches wide, without the Porta, i would still be there right now...

if you dont want to just shell out the bucks to buy one right now, i highly reccomend renting one first if you havent used one before... you wont be dissapointed...
