I think this is a great suggestion. I have seen plenty of cases where $1k will buy something that originally was double or triple that in cost. Lots of Facebook groups for used smokers and Craigslist is an option as well.I use to drive an Old Country "Pecos" and I can testify that they need work when you get them home.
For the money you are considering spending, I would search Craigslist for a used higher quality smoker.
Here in Austin, $1000 will buy a used $2000 smoker.
