Diesel Bombers - gas nailer's ? hitachi??

who around here is familier with gas nailers? everyone around me uses pasloads, so i just assumed that, it is the way to go. but i got to looking around and i saw that Hitachi has a gas nailer, it looks pretty sweet, but i can't really find any reviews on them. i am always up for trying new tools, but 300-400 on a nailer,(when i already have one) is kinda hard to let go on a hunch. so my question is: Who around here uses gas nailers on a regular basis, and which ones you use, and what are the down falls. the hitachi's seem to be priced the same as a paslode, but are they as nice. the experiance i have had with paslodes, are they don't seem to hold up to abuse very well. they are great for a quick job, but with contuious use they seem to fail at an early age. any sugestions are welcome!!
