Husqvarna or Stihl. Better tools to start with and you will still be able to get parts for them years down the line. Makita and Echo are now coming through as dependable brands. Jonseerds are old Husqys rebranded, not very civilised saws, more of a farmer choice of big and powerful pig iron.
Small Stihls tend to be cheaper, though I am a Husqy man myself for all out power and durability, though tend to be a bit heavier.
Check your local chainsaw dealer for a second-hand machine. Heavy users like ourselves p/x for new saws every 12-18 months. Better saws at a fraction of new prices that will easily survive a more gentle pace of life.
EDIT: I know Husqy won’t warranty online sales, similar to Trek?
