I get most of my meat from my local Morrisons, usually really good. They tended to only have rolled briskets but they now do a pastrami style brisket, it's great because it's flat so you get a really good idea of the size of the joint, and it's got a great marinade with it. I've smoked a couple now and have to say I was impressed, lovely and simple if you want a very quick to prepare piece of meat to stick in the smoker. Ok they're not massive but they're a decent price so I have purchased 2 or 3 each time I've done them.
