a replacment condenser will also require regassing, normally by a professional. Especially if your car uses the newer R1234 YF gas . (which is not so widely available and at least twice the cost of the old stuff) It might be worth checking if an aircon specialist can get the parts at trade price and possibly supply,fit and regass as part of an inclusive deal at a good price . With them taking responsibility for any problems, leaks, repeated regassing etc.
