Have you received it from Fishpond yet or just ordered it? I and others have found them very hit and miss on actual delivery of products.

I noticed their USA supplier has Sentinel for $41.71, save $34.28 (45%) on their website at the moment with free shipping but Fishpond themselves have it listed for $65.97, save $34.02 (34%). The USA supplier may be better at delivery than Fishpond too.
