I have an old Kubota B2150 (aka Norman - there were enough girls on the farm!) that I woudnt be without. I was a total novice when I got him, and certainly not a mechanic, but, to date, he is simple enough to fix when I break him and servicing is pretty straight forward too.
Ideally I'd have got something with few more horses but Norman has been up to what ever I have thrown at him. My only word of caution would be you will need somewhere to store the tractor ...and any implements you get... up here the implements seem to be multiplying!
