I can second Tom's view of Amphibian, in Norwood. James always has time and opinions, not always good ones but frank and honest. If he likes or dislikes something he normally has a reason, and I have not known him to rave about something just because he has it on the shelf. His prices are also amongst the keenest I have come across, for example he quoted me his standard price for a Buddy Commando TD before the dive show and I couldn't beat it at LIDS!
Can also add to the ravings about Denny as I have spoken to Chris a few times for advice and equipment ordered has always been delivered in a timely fashion.
As for my 'localist' of LDSs, they were pretty ropey anyway but I stopped using them completely after the guy there was adamant the drysuit I was trying on fitted perfectly and was how it was supposed to be - not withstanding the fact that I could have sang soprano if I had been trying to reach the valves for a shutdown.
Regards
Mark
