Depends on if you want HD or not...
As far as motorised system goes.. I set mine up about 3 weeks ago.. It was tricky but got a lot of help from digidude, He has a great tutorial on this site somewhere..
If you can use a drill and a level and a few spanners it'll be no problem and very satisfying when you actually get it set up..
I got a TM6900hd with a motorised 90cm dish and i'm delighted wit it..Hope this is a bit of help to you
