Yup. Great saw. I had a 310 for years and ran a 290 a fair bit. (I'm sure you know, but the 310 is identical to the 290 only a slightly bigger piston.) If I were you, I'd spring a little extra for the 310. I loved that saw and it served all my firewood needs very well. The only reason I upgraded is because I could, and wanted to. Otherwise, that 310 would still be suiting me just fine. Very durable, reliable, easy to use. Maybe a tad on the heavy side for the power outuput, but you have to go pro level to fix that - it's part of the $$ trade-off. And the weight really didn't bother me all that much.
There are some on here that dispise that series of saws, mostly due to their weight. Sounds like you've been poking around here a bit, and have picked that up. I have always thought they are applying their standards/preferences to other's needs. Having been an owner, I think you are wise to go that route.
Buy it and enjoy.
