Looking for a good bitz site

Hi!
Where do you guys buy your extra bitz when it comes to the finecast range? I myself buys most of the bitz from http://www.bitzbox.co.uk/ and is over all quite happy with them. But they lack the resin boxes from the GW range. I get it why sites don't buys single mini blisters but there's quite many 5 man boxes out there =/
So I was wondering, where do you guys buy your resin bitz? I just need the Mirror swords in the Howling Banshee box and that's not enough for me to buy a whole box from the store =/

Never seen any resin parts on a bits site up until now. No idea where to look mate. Sorry. Maybe others can provide more useful information.

Here is one I have found, cant say how good it is (never ordered anything from it yet):

Spikey bits is a pretty good site as well.
