I was looking to get into something that was new enough that it would not need to constantly be worked on, and would last a few years. I have looked at several pre t-2 6620s, and all of them had a lot of hours on them and showed signs of poor maintenance. I would not be opposeed to a pre t2 6620, if it had been well maintained, and had low hours, but I haven't been able to find a 6620, t2 or other wise around here, that I thought was worth taking home.
