A very nice earl grey (if you like stronger tasting teas) is earl grey bravo from adagio http://www.adagio.com/black/earl_grey_bravo.html
Good tea is cheap, you typically just mail-order a good quantity at a time and keep it in an airtight tin. The samplers from Adagio are ~1 oz., and a great way to try out several for a few dollars each.
I don't know how much a month's supply of really good coffee costs for the fanatical drinker, but I know my monthly budget sure wouldn't get you far at Starbuck's . . .
