For many years I had a smoker that I built myself, rigged from an old freezer shell & electric hotplates. One day it shorted out, and started an electrical fire in my shed.:ko:[rofl] Thank goodness my homeowner's was paid that month. After that fiasco, I bought a Smokin Tex, works great, had it 5 years. A buddy has a Smokin It smoker, which is basically a rip-off of Smokin Tex, and his works fine. The only thing is it holds the moisture in (no dampers), so I bought their drying fan for making jerky, comes out great. I don't keep it in the shed anymore, I keep it on the back porch (covered awning).
I've been using the Bradley for about 6 years. it is very easy to use but it is not the cheapest. their patented smoke generators only use their wood pucks which can be pricey but you can get them cheaper on ebay or even from homedepot.com. I know there are a couple of deer processors on this site who use Bradley for their jerky and smoked sausages. temperature control is critical when making sausages as temp spikes can cause the fat in the sausages to render, resulting in sausages that have a dried cardboard texture. ideally, you should use an aftermarket temp controller if your making a lot of sausages. pm me if you go with the Bradley and I can point you in the right direction with equipment and setup.
this is my smoker setup. I put it in a garden tool shed mounted to a dolly. I leave it in my garage and just roll it out when smoking. you can see the after market temp controller that I use from auber instruments made just for the Bradley. it holds temps to +/- 1 degree which is real important when making sausages. I do all my venison sausages, snack sticks and bacon in here as well as pork shoulders for pulled pork. I never had to replace anything in 6 years but I don't use it every day
I have a Masterbuilt and use it a couple times a month. I love it. Super easy to set the temperature and walk away. Whatever you get make sure that it uses wood chips and not manufactured wood disks. Electronic controls are nice too. A glass window adds to the cost and will be covered with soot so you won't be able to see trough it anyway.
