hi,
firstpersonview.co.uk will sell a ready to fly package but you will most likely have to put the bits together (physically on the airframe). Believe me when I say that it's not that hard. Even I managed it.
If you want something that literally comes out the box then speak to a local model shop and see if they'll build one for you.
However, I would suggest that the more you put into putting it together, the more you'll actually understand about what it's doing and therefore be able to diagnose issues (should you come across any).
I've had great response from fellow forum members for help.
Simon from Firstpersonview.co.uk has been great too. He recently provided me with a black pearl, Plug and Play cable (for mini iOSD), immersionRC 600 and Spironet antenna's (fitted by myself) courtesy of youtube and command strips. I would have bought the rave creative monitor bracket from them but they were out of stock and ended up buying direct from Rave Creative. There was zero soldering involved (some minor cable fitting, all very much plug and play).

Fantastic service from both the above as they were delivered within 2 days of ordering on Bank Holiday Monday.
My local model shop is brilliant and means they will always provide assistance should I need to walk in (which I've done a few times). They sold me both my vision and my P2 with H3-3D and mini iOSD.
and amazon provided the Go-Pro Hero 3+ black.
Yes i'm stupid and asked the dumbest questions imaginable :? However, everyone has been really helpful and after calibrating the compass I took it on a flight about 1hr ago. No video unfortunately as the Go-Pro decided to have a "won't power up" wobble, which was fixed just now by bringing it back, removing the battery and plugging in the USB charger for 10 or so minutes until the light came on (I didn't remove the SD Card). Pushed the battery back in whilst the actual camera was charging and we're ready to go again.
It wasn't difficult to put together and once you've figured out how (ask questions and use youtube) you'll find yourself understanding how your Phantom is put together.
you WILL need a decent screwdriver set. There's a few recommendations elsewhere.
EDIT: I forgot that I have also contacted Marionville Models. They were really helpful and responsive too. They've also got some really good explanatory installation videos. Just do a YouTube Search.
