Egyptian Maus cost roughly about the same cost as a Maine ****. I got mine for around £450.
I know that Makunouchi got his Maine Coons for around the same price and I was most impressed by his 2. If I were to buy a Maine ****, I would almost certainly buy from his breeder.
Incidentally, I was looking at Savannah breeders yesterday and I know a few people on this forum are interested in going the Savannah route. F3 Savannahs can be had for around £600, so the prices are coming down to acceptable levels. My problem is that I only want an F2 Savannah (this shall be my 3rd and final cat, ever) and right now there are none for sale in the UK, so I must wait.
