Well ... I appreciate all the advice fellas. I ended up ordering a Dolmar 5105-20" ... $455 shipped, includes a case also. Now just the wait, but hopefully it gets here by Wednesday.
Hopefully it holds up and cuts as well as all the reviews I've seen. Seems to be a very popular saw in Europe, especially the Britts. After reading some UK posts, sounds like Makita did rebadge the 5105. It's called the DSC5303 (DCS stands for Dolmar ChainSaw)... but they were hard to find here and cost about $100 more than the Dolly (apparently that's what the Britts call the Dolmar saws).
The other 2 saws looked like great saws too. In the end, I can afford ONE saw right now, so a 50cc "pro" quality saw makes sense. And, I just couldn't overlook value of the Dolmar.
Congrats, let us know how it does for you.
