I have limited input for recommendations for seeds and seed banks but I will add what little experience I have.
My one and only order for seeds has come from Attitude Seed Bank UK. My order was placed in June 2011.
I ordered 10 feminized White Widow seeds. I added the options of a crush proof shipping tin wrapped in an additional Attitude shirt. Shipped internationally to the east coast United States. The seeds arrived in about 15 calendar days from the order date. The shipment was very well packed and I noticed no damage. Barring anything unforeseen, I would recommend Attitude based purely on price and efficiency.
I have yet to germinate any of my seeds as I am still getting my first grow room finished up but as soon as I do, I will report back with my success (or lack thereof) once the seeds go in!

edit: I forgot to add cost. For the 10 seeds, tin, shirt and international shipping....total was £111.49.
