I think stainless rims are like anything else, if you buy cheap and nasty ones that's what just you'll get, but if you buy high quality (and fairly expensive once landed in OZ) ones like the Devon rims from the UK you'll be very happy. I've just received two sets of the Devon rims, one set for a Mk2A and the other for a Mk3, and they're a very impressive product. The dimples are the correct pattern for each wheel and the spoke angles are all perfect. Devon make their own rims in the UK (I believe they're the only people who do so) and definitely know their business. I certainly think they would be made of an appropriate grade of stainless for the intended puspose. Personally I like the idea of stainless rims, as they keep a high shine, last forever, and any marks can be polished out. All that said though, if someone else would keep them clean and polished for me I'd love a set of flanged alloys - as they just look the business.
