in my personal opinion dont order at Silverman's as they are rediciously overpriced (e.g. £75 difference in exactly the same rucksack!! £7 on 95 trousers and £30 on 58 webbing!).
SASS is a gd supplier I found. Got my shamagh, snug 3 (although misleading description) and basic PSK from them.

But there is an even better (cheaper quicker) service out there. It is UK based and (cant remember exact) something called like Starmans. The extra advantage if you order with them anything over £25 you get to chose a PROPER free gift. If you order anything over £50 you get something to chose for free like a set of mess tins! Now that is service!

If only I could remember the URL....
