Thanks all. Deader than dead Stig.
GP, the Stihl battery saw has less power but makes a neater pruning cut with that tiny chain. The Husky is great for limbing and logs not wider than its guidebar. Beyond that sucks the battery pretty fast. Does not make you any more productive, but the thing is you get used to the quietness, no tickover, no pullstart, no gas etc. You switch it on and off with your thumb as you pick it up or hang it back on your saddle. You can get a ton of work done and nobody even knows you've started. I was fortunate that I got to borrow one before I bought
....but soon realised it was well worth the money for me. Cant speak for everyone else but I like it a lot for the reasons above. Next best thing for me is a ported MS 150 which I have. Like an angy wasp when you mod it. Brilliant.
Wouldn't waste money on the echo
