If you cant afford to buy a new Xray then buy something else!!!
As for durability, my 1st Xray was a T2 and that was in 2006, i bought some spares at the time just incase i broke something. Ive since had a 007 and now have a 5cell and 6cell 008 and still have 98% of the parts i bought then. I dont even bother bringing my spares anymore because of how strong the parts are.
