Well, agreed that the AMS RLD is utter bull shit, im not even going to try to defend that. It has become a massive tourist attraction, hence the dilution in quality. I think, if you have a decent experience in punting and some money to spare. One should be able to easily avoid the RLD's anywhere, as most are crap. The only one that carries a decent reputation is dusseldorf.
The next time you do visit holland, i suggest going to the prive huis's and you can find OWO, DFK with very good quality women for 120-150 eur/hr. You may also wish to try the dutch version of AW which is kinky.nl, there you can also find a few gems. In my defense, i think the price is cheaper in holland with certain WG's, you could pull off good quality (OWO,DFK and safe) for 80 eur/30 mins quite easily.
@adindas: yes sir, i looked at it. It seems to be very useful, although i dont live in london but close by in reading. Im a quite new to UK punt scene, so... its going to take a while to get to grips with it.
