It's your money you earned it you spend it how you see fit! I looked at one of those just out of curiosity the last time I was in Homo Depot. IMO there are better options for that amount of money. It is very thin Tin , it is drafty( don't seal well) and the fire box is to small for the size of the oven. If it was me and I was on a tight budget and needed more cook space. I'd get a pair of Masterbuilt ECB's and Mod them. You would save enough to fund the first cook and have a Nice supply of good cold Beer to enjoy in the shade and smell the smoke.
