Can you recommend any of these gear dealers?

Part of building the Music Thing Shop is finding 'partners' who'll actually ship the stuff out and take your money. I'd be very grateful for any feedback on buying from these companies:
• Sweetwater
• Musician's Friend
• Dolphin Music
• Thomann
• Zzounds
• GearTree.com
• GAK.co.uk
• Audiomidi.com
• Nova Musik
(And yes, I know that Analogue Haven is cool, and we're working on doing something together)
