Welcome to the forum!
If you have been looking around the forum you will have seen some excellent build threads and ideas.
Suggest you don't go for 1.9 if you can help it, I know tax is an issue but also think of resale.
I think your mate might get the better deal as he will practice on yours first!
anyway it would have been great to have someone helping me out on my build so am a little jealous.
If you need advice just post on the thread, we are a friendly bunch and always willing to help others, as we have all been there and appreciate what you are taking on
Cheers!
BTW - There was no manual for the build and my build was my first, so if I can do it anyone can!
