Brushless or not

[tc2k]

Im currently trying to get my B4 up to a better race standard and Im wanting to get a nippier motor than my Peak V2 19t motor I have now. I was looking at 2 options, either buying a Novak GTB Brushless set which would cost a hella money in the beginning at around 170quid or, buying a decent 12turn V2 motor for around 40quid and then buying a lathe which you can get for about 50quid and then buying about 7 or 8 sets of brushes for about 30quid. This way would be cheaper. I know the brushless will outlast the Brushed but 1. Ive heard of alot of Brushless have problems and go pop and 2. its a LOT of money to spend on one piece of equipment. Im leaning towards the lathe/brushed combo but whats everyones opinion.
