Hi Dubwrightly,
I'm in Moray and it took 3 years for an agricultural field to come for sale. It cost about £6000 an acre, purchased through Aberdeen and Northern Marts.
In desperation to find even a couple of acres, I looked at building sites and if there was anything of interest I asked the agent to find out if the vendor would sell an additional few acres. Surprisingly, a lot would, so if you can face building a house, that might be one way of getting your own holding on a few acres.
Good luck.
