Giant Tancex1 rear triangle wanted

Hi Guys

I need a rear triangle for a giant tancex1, year 2008, medium size frame.
I have wore through the chainstay on one side from ankle rub on my MTB.
Looking for a cheap solution!!
I have asked the local bike shops for pricing but need to check all avenues before I go for a new part.

Cheers
Have a word with Alfy. But when you get a new 1, you need to change your cleat position, big time
