After 5 yrs, the auger tube at the firebox rusted back leaving a gap on my Lil'Tex, model 075..It was a "made in China "unit. It was always under cover and covered when not in use..The powder coat finish developed some small rust spots that were ground out and painted when first noted..I kept it waxed, 2x/yr....It did indirect cooks well..
Did I enjoy it? For sure. I learned a lot..Would I do it again? NO.
It is hard to justify a premium pit..The high end units are better built and usually have more features...
Look at the whole picture; Service life,parts validity,service,how it cooks,features,easy to maintain.....
I ended up with a Memphis Pro. It is so easy to clean..Heats fast..Well there is a long list of good..
Any finish, powder coat ,paint ,porcelain etc, if chipper or scratched will expose the underlying metal to the elements = rust..For me stainless is the way to go. It does require upkeep to keep it looking good and prevent staining.
