Hi Christy
We are along the front range (south) and havent been able to find many Guernseys either. Most of what we have seen hasnt been worth what they are asking. seems the premium for the a2/a2 and Guernsey name really drive the prices up.
we always wonder how much of the cows condition is management and how much is genetic - but i dont have a good enough eye to tell the difference.
also, remember no one will sell you their best cow
we have taken to only keeping cows that were born on our farm, even if they are not purebred this or that.
Good luck
