Dude, as its your first brush you can get a really good quality one for MUCH less money. Theres a UK independent guy who sells silvertip badger brushes for a fraction of the simpsons ones. Google New Forest Brushes. They really are good.
That would be Peter (Fido) and he used to take shots at Simpson every chance he could, they're not much different than TGN and I'm pretty sure hes getting the same rod stock that Tony uses as well.
