Hi Larry,

I use Oklahoma Joe's Longhorn (2 years already) and I'm pretty happy with it. It's a bit on the pricier side considering your budget (currently it's about $450 on official website), still it's a decent unit. I use it quite often, especially during the weekend, and I find it really meditating - firing it, stocking and relaxing with a beer around it. It's quite heavy, all steel, wide and the cooking area is big: like, it makes really good food and it's what got me addicted to BBQ. 
But need to mention, It is my first smoker, so take this will that grain of salt. Ofc I read some reviews before pulling the trigger, the price was right for me and I must admit - I'm still learning to use it (it's not just a hobby or cooking method now, it's an addiction according to my wife).

Good luck choosing!
