By gum, there are no bargains in Mac world are there? Don't know what the number of households with five Macs might be, but I bet it's considerably smaller than the number of those with two. I guess this pricing structure is designed to tip me away from the repair option and towards the new purchase option. Being a bit of a cussed old soul, the actual effect it is having on me is the opposite. I've found a local specialist near Bath (which is just a few miles away from me), he's going to assess my existing machine at no cost. I will pass on all the information I have received from you guys on macosx.com. I really cannot thank you enough. Best wishes Tony
