The only electric smoker made in the USA I am aware of is from CookShack. The Smokin-it ( SI)and SmokinTex (ST) which are all stainless steel in/out and resemble the CookShack are imported. SI relocated to Michigan and prices on their model 2 and 3 are scheduled to increase on 15 April 2015. I do not know by how much.
CS offers refurb units with a full 'new' smoker warranty. Also, if you go through PayPal, you can stretch the payments to 6 months with no interest, which may make it easier on the budget. My CS 066 Amerique has performed flawlessly, but was expensive. The SI units are built solid, and are very dependable. My brother has the SI3 and has been using it since 2012 with no problems. Shipping on them is expensive (it is explained on the SI site).
There is a company (R&V Works) that makes a propane smoker called the Cajun Express Smoker. American made. They have a 4 rib, 6 rib and 9 rib model. The link below shows cooking times for various meats. Pretty impressive. They are pricey, but I suppose the quick cooking time is a valid trade off for the cost.
