good obsevation AERO , LOL!! I had not noticed the date of the original inquiry. My previously post still applies I think:

"Alot of good info , pros and cons , and comparisions here. I say nitro is cool for the noise and smell. electric is cool because it is easier, quieter, and definatly cleaner. In either case Speed is directly proportional to the depth of you pockets , the thickness of your wallet, or the number of "swipe here" that you have on the credit/debit card "

I also wonder if he still has the need to know?!!!
