Well like you I did them myself, and just the whole process of measuring each one so they'd fit in my smoker, tying each off (busted a lot of cases), then smoking, then finishing off in the oven, then cutting into pieces to vac seal...just a lot of work for one guy, but they are good! And an electric stuffer would help a guy do it himself.
I recommend getting high temp cheese and dried jalapeno flakes. And like muddy dogs said, might need to add moisture if its not coming out of the tube good, that cure makes the meat set up pretty quick.
