The Solo 650 is in the same class as the Stihl MS250/025 and Husqvarna 350. It is a good quality saw, but has some compromises in construction that lend itself more to the heavy consumer/farm user more than the proffesional user. Mostly it is the plastic cranckases or crankcase bottoms, but other things like spur sprocket and plastic chain catcher built into the clutch cover are items that come to mind with the SOLO.
SOLO builds quality equipment. They have to in order to offer a 2 year warranty. The 650 is a far cry from a Poulan or McCulloch that you by at Wally World. The power to weight and dispacement you get from the 650 makes it pretty attractive at $200. It probably will not have as good of anti-vibe as the Husqvarna 350, and there is not much better than the Husqvarna air injection for keeping the filter clean, but other than that, I would put the 650 right in the hunt.
Standard features on Solo Saws: **High power-to-weight ratio **Nikasil, silicon carbide coated cylinders for durability **Anti-vibration system for comfort and reduced fatigue **Easy-start primer **Eco-matic oiling system - Delivers no oil at idle and increases delivery along with higher RPM. Fully adjustable too! **Finger-tip choke and throttle controls **ANSI safety features including chain brake, hand guards, chain catcher, throttle interlocks, and reduced kickback bars and chains. **CD Ignition **Automatic half throttle choke setting for starting ease **Compression release included on 636, 645 and 650 saws **Two piston rings on models 645, 650, 651, 662 and 694.

The Solo 651 would be the model to compare against the Husqvarna 353 or Stihl MS260/026.
Dolmar builds only saws with magnesium crankcases. It is hard for Dolmar saws to compete pricewise with the middle of the road saws like the Stihl MS250/290/310/390, the lower end Husqvarnas 340/345/350, or the lower end Solos like the 650.
The Deere saws (CS series) are made by EFCO/EMAK in Italy. They are a pretty good saw. Magnesium cases, good power to weight, good warranty, but have sort of a cheap feel to them, and lack some of the modern ergonomic designs of Stihl and Husqvarna.
