i'm not......you are one of the few that has not been impressed with the 7900. some like other saws better, but nearly all give the saw high praise.
The saw cuts - just not much better(if any) than a DP 460, yet weighs a bit more. I'll have a 7900 buried in 40" maple this weekend if the weather is decent. We'll see how she does then. Perhaps she'll redeem herself. However, the main selling point of a 7900 is the 'light weight" and perhaps the affordability, which it doesn't really have as much as people think. In my neck of the woods, people ask for the same amount for them as a 460mag if used and in good condition, so choosing a 7900 is a bit of an ask. The saw certainly is no lightweight compared to a comparably powerful saw. This isn't just my feelings, the owner expresses the same opinion, and he owns and uses quite a few saws.
