A couple of my favorites:
I really like darjeeling, specifically from the Makaibari estate:
Upton Tea Imports: Tea - Makaibari Estate FTGFOP1S Second Flush (DJ-142) (TD40)
This green tea is truly divine:
Upton Tea Imports: Tea - Long-Jing (Lung-Ching) Green (Superfine) (ZG71)
Good call on the kettle - I just bought the same one a few months ago for work, and it rocks. Totally worth the price, especially in contrast to the crappy cheap one I had. I use bottled water - the water at work is filtered, but still incredibly hard...leaves crap on the inside of the kettle, and makes for nasty, muddy tea. I use a single serving cup with a filter basket and a lid.
