I got one of similar to that from Goodwill a few years ago. Cost me $5 and then I spent another $50 or so refurbishing it. It never worked that great, nor could I get the dog smell out of it. After relegating it to the barn for five or six years, I finally donated it a little over a year ago to the church I was attending at the time for their rummage sale. It has not been missed.
I hope yours turns out better. The price was certainly right.
