I've recently had to replace mine, got it off ebay £92 plus a tenner p&p and it arrived overnight. It was OEM made by Nissens in Denmark so is of decent quality. I also replaced the receiver/dryer at the same time got that off Wannapart £35 delivered OEM by Hella, so again decent quality.
Saved a fortune over genuine MB (£300+ for the condenser and £90+ for the receiver/dryer) the only thing I had to buy was 'O' rings for the dryer- five bloody quid from MB!
PS Hope all is well, I'll hopefully be getting the old girl over to you soon for her respray. See yours is shaping up nicely.
thanks guys got a very good qoute from euro car parts they give some really good deals and not going to buy from MB have spent a fortune with them this month
