Have heard good things about their pro grade 501p. Bought one for my brother, on sale $400 with 20” bar and a bit over 10lb iirc.I have the 620p as well and I love it, can run a 28" bar with a full skip on it.
I run a Husqy 390xp for larger wood up to 42" bar.
I'm thinking on buying the new Echo cs-490 as a lighter saw for in the tree rear handle to replace my cs-400.
Check it out here... Echo CS-490
