Search for land is proving to be painful

Went to Scotland on holiday for 12 days and had a look around Caithness. It's the place to be and we found the dream land in the dream location at Roster, made an offer and lost it.
So we know we want to live in Caithness, but land prices seem to go up by the minute.
The land we made an offer on at Thrumster, before we even went to see it, was declined and the seller now wants offers over £60k instead of £40k. Ridiculous.
There is however freehold land of some 29 acres (12 hectare, 18 football pitches, 117334 sqm) at Mybster which is not on the open market.
We are waiting for a detailed plan as the land has some pylons and wires running above and below. If we can build a house 150m away from any wires we will consider buying it. There is a wind farm visible in close proximity with 21 turbines on one side and another one planned with 30 turbines slightly further away on the other side. The turbines don't bother us though.
