I've owned or spent considerable time using a JD ~56cc, Echo ~56cc, Stihl MS290 (again 56.5cc), Stihl MS250 (~45cc) and a Dolmar 7900 (78.5cc). Each of these saws was the only saw I had when I was using them. Unless I'm going to climb, I'd take the 7900 every time. It may be a little heavier (esp. with the 28" bar) but when the job takes less than half as long, the weight seems like a non issue. Plus the vibration control is awesome. And I just love a 28" bar, perfect for cutting smaller stuff on the ground without bending over. If I had all of these saws at once, I would probably use the 7900, 95% of the time and the MS250 5% of the time (for climbing & overhead limbing) and never touch the others.
