Looking to buy a vRS pd!

Hi guys, I've found an octavia vrs tdi pd that I'm hopefully going to purchase this week. Its got FSH and recent cam belt and clutch change so hopefully it should be reasonably reliable. I've been reading up on the injector issue and how expensive it is to put right but all the threads are very old. Is this still an issue I need to worry about and if so how do I avoid this issue. Are there any other major issues with this engine. I've looked at as much as possible online so hopefully itll be able to make the correct decision. Cheers, James
