In the UK, you can't go wrong with this one, it's what I have:

Has 1500mA on tap, useable at 100v-240v, it's regulated and very quiet. That should be enough for 10 pedals, but if you're right about the 500mA draw from the BSW you may be scuppered, although that seems excessive to me. It works fine for my 5 pedals, but I can't guarantee it'll be able to power your collection.
They only sell daisy chains suitable for 8 pedals with straight plugs though, so you may be better off getting a daisy chain elsewhere. On ebay you can get leads with right angled plugs for 6 pedals, 2 of those would do the job.
