Thanks again for the replies,
I should of put a link to the ones i was looking at, sorry about that.
These were the ones i was looking at:

When i asked them about them, they said that they are the generic version, but they are virtually identical to the Celestron ones
The mount will also be sitting on concrete.
Interesting reading through the report also, I am now just thinking if there is much difference between the generic version i posted a link to and the Celestron ones apart from the huge price difference?
