Buy the Ion, change the feedneck (smart parts q-lock is great!), get a decent ASA (take that damn duck bill off!), stick a decent hopper on it (Egg at least), a good air system, and you're ready to go!
These rock for the money, but rock better if you spend a little pimpin them!
For £400 you can't really get a better complete setup, and it'll all be brand new with warrenties etc.
