stilh or husky and also echo but make sure your local guy is a specialist in whatever you buy, mines a stihl guy and even though were pretty isolated he can get any thing in a matter on days and knows the system backwards, also chucks in loads of freebees and info to boot being local he wants to keep the business and to make a saw of any description work year after year it'll need a service. we have a lot to work on so I got
a fs410 to start and would not look back, it'll cut through anything including bamboo! although I have been using other stuff for some years first, you need to work out what your going to use it for and don't under power the job, otherwise you will put strain on the machine, and it wont last as long as it should.
but that said I also have a goat, well several and i find putting them on a 2 mt high really brambly bit the best slotion of all, then cut after with a crescent shaped long handled slasher is really effective, and much cheaper!
good luck
