What you are asking relates to what shoes do I buy..It is extremely personal.
Some considerations could be; service*,parts availability, ease of maintenance (a must for a pellet pit),finish ;paint and powder coat can be scratched leading to rust. Stainless isn't maintenance free, but close depending. Warranty. Size - height/width /depth. Tables/shelves. Double walled for cool and cold weather. Does it look right to you?. Have you seen one in person?
* If you are new to cooking with pellets, there is a learning curve that combined with any pit problems makes life more difficult. Communicating with factory service can be a big help.
I would send you my magic wand if I had one.
