Hey I've got a T-Mag myself and it's been really good to me, it's one of the older ones (got it soon ofter it came out) and the frame is perfect, no stress marks so the newer improved one's should be great The freewheel's don't blow up, they just fall apart and skip as a £12 ACS would, i whacked a Tensile (£35) and a mate of mine that has a King says it feels lovely so deffinately go for one of those An Echo Hifi stem, and ZOO! bars totally change the feel of the bike, for the amount it'll cost you, it's soooo worth it ! So nothing that'll actually break badly, just a few things to upgrade A.S.A.P as the factory parts suck ass Hope that's reasurred you a bit Joel
