HI mate welcome!
that Orion scope is good value but at f3.9 would be a bugger to collimate if you weren't that confident.
Andrews communications have GSO or SW newts that are about the same or f5 which would be a little better.
You need a decent mount to go with it- like an EQ 6.
What about some of the packages at Bintel like this

There is a lot of wisdom on this site with these mounts and these type of scopes.
Also have you been scouring the classifieds?
Welcome to the money pit!!
Have fun
Graham
