I've been coming to london since the beginning of the nineties and if you ask me the scene was amazing in the beginning round about 93 and then collapsed round about 97/98. countless recordstores went bust (zoom, unity,silverfish,phatcat) and others stopped selling techno like vinyljunkies... Now one the only decent ones left is Eukatech (i know same owners as silferfish)....
Lots of organisers stopped there techno nights (maybe they just moved but i didn't see as much choice in parties all of a sudden)

Now it seems to be getting a bit better then it was but it's no where near what is was.... I used to save money and buy shitloads of records when i went to londen... now I just check the stores like eukatech and the second hand stores for old stuff, but i buy most in holland... namely confused records in the hague....
very frustrating because about 60% of what i buy is english!!!!!!!!!!!!!!!!!!!
