My car had a full gearbox rebuild by the VW dealer in Canterbury in August 2004 a few months before I bought it costing £1400. Unfortunately, one of the new bearings decided it had had enough less than a year later, which caused the box to implode on my way home up the A90. I bought a replacement one from a breaker, had to take a gamble on it being in good condition, and to be honest, it wasn't in as good condition as I'd hoped for but I was able to use enough parts off the fubared box (most of the bits were under a year old) to make one complete box in good condition.
