As above prices are inconsistent. I've seen them up for over 2k and as low as a few hundred. If you have the ability to do work yourself it's got to be worth a punt but they're into the realms of expensive work. We spent over 1k on ours. When we sold it it needed a new rack long term, belt was due, eml was on etc... Got £550 it after sitting for a year.
Even at diy money it's a gamble IMHO. Quite a lot of specific parts.
Gearbox was the best part of the car. A bit notchy when cold if anything.
