Hello , ilovesmokingmeat..., before going and spending a lot on a "Packer Brisket" , do a few more Chickens and some Pork Butts. Brisket is so much more involved and costly as it ups the "Anxiety factor" when trying not to mess it up...
A few Butts, Fatties , Chicken and such , will improve your skills to the 'Brisky' level in no time...
Have fun and practice ,practice , practice... oh, and...
