I've purchased every bit of my gear from B&H. It is the best, in many opinions, in the US. They are closed because they observe the jewish holidays and sabbath very strictly.
I just purchased the Canon 24-70L and had it delivered in the UK. The tax, handling, VAT, etc still came up cheaper than buying here in the UK. ($200 on a $1149 lens--minus the $100 US rebate) Normally, since living in the UK, I will order and have it shipped to a friend in the US who either sends it on or I go pick it up (yes, on good days, the airfare still makes it cheaper and I get to make a shopping weekend out of it.) This instance was the the first time I actually ordered and had it shipped by B&H and I wasn't sure what to expect, but is was an okay experience. Maybe I had a sympathetic sales person, I don't know...
