I used to get my malt from Tuckers Maltings, too. I was very sorry to hear they'd thrown in the towel. They used to have an exellent beer festival and bottle shop there, too.
I like the way Geterbrewed do things: a kilo of malt costs one twentyfifth the price of a full sack of malt, for example. I like the way they sell the bulk hops, too. Watch out for their crystal malt designations, though, as Crisps would seem to be different from anyone else. When I can't get what I want fro GEB, I go to THBC. Again excellent prices and service and I like their Hookhead malt, too. I started with Malt Miller and BrewUK, but they've priced themselves out of the market as far as I'm concerned.
