Ok, I don't usually do this sort of thing but I'm making an exception here...
Last Monday I ordered some mags from HKSpecialist.com cause they seemed to have the best price on 30 rnd. curved factory mags. I ordered late in the day so they shipped on Tuesday, Priority Mail. They were waiting for me on Thursday. Well I needed more help than just curved mags so I called Friday afternoon to order extractor, extractor spring, and ejector lever. The guy answered his cell phone and was on the road to some shooting activities. He pulled over and took my order. The stuff was waiting for me when I got home on Monday. Not sure what he did to take care of it but I thought that was pretty cool.
I was sort of on a tight schedule as to find out if I could get my new (to me) SW5 working reliably enough to spend the extra money to SBR it. My appointment with the sheriff's rep. is this Thursday so I was in a bit of a hurry. I never mentioned this but they expedited the orders anyway. Very nice.
Anyway, if you're thinking about getting some real HK accessories and want to be taken care of quickly, it looks like this is a good place for it.
