Hi Ian
My prices aren't too far from the HK prices and some cases the same...So far I've found CORE and ZCI gears offer pretty good value.
Here's what I can do for the forum members...If interested message me online and I'll get back to you.
All SHS Supershooter gears for £23 all in 1st class, same or next day delivery.

Personally I've been really impressed with the ZCI gears, but also haven't been able to fault the CORE or SHS one's yet.
