Hi Ozfifer,
Having very recently travelled the same path, I eventually settled on a 10" GSO Dob from Andrews Communications (see Luka's message). I was impressed with their help and service, the scope was here in 4 days.
If you you opt for the premium crayford version of the 8", you should get change from your $600
, and the freight is on them - about $300 to our end of the world.
Good luck,
Keith
