I've been using the classic air graver with the foot peddle 40 to 50 hours a week, fifty weeks a year for the past eight years. And during that 20,000 hour run there has never been a second that I regretted buying this tool. So far the cost of the tool is about 6 cents an hour and every hour I run it the cost of the tool continues to go down.

So if you can find a used tool go ahead and buy it with the assurance that it will be worth the price.... if you can find one. I have only seen them available on a few rare occasions.

On the other hand, just go ahead and buy the classic with the foot pedal today. The money may seem like a lot now but in about eight years it'll seem like the best bargain you could ever have gotten.

Since I live and work most nights in a condo I have a silent compressor. If noise is not a problem go to home depot and get a decent sized compressor for a few bucks. But is the noise is a problem the silent compressor will be the expensive solution. It makes noise when running but its not loud at all. I got mine from Steve and the only problem is I got one with a small tank so it cycles a lot. But I've also taken it to work when the store air compressor had to be replaced and it ran the three Lindsay engraving tools we have there without any problems. However the CO2 setup does sound like a great way to get air silently.
