I've owned my Rec Tec for right at 2 years, and I really like it a lot! It's well-made of heavy gauge steel with all stainless interior parts. The computer brain/temperature controller is rock solid. It'll hold any cook temp from 180* to 500* within just a few degrees by the simple push of a button. It is also a very serviceable high-temp searing grill, especially with the addition of the the Grill Grates searing kit (which I believe is included in the Kitchen Sink package).
The most common complaint I hear from folks who don't like them is that there a less heavy smoke flavor than you get from charcoal rigs or stick burners. It's true that, because the pellets burn very cleanly, these rigs don't make as heavy a smoke as other types of pits. If you haven't eaten food cooked in a pellet cooker yet, you might want to find someone who has one and taste some of the meat it produces to see if it suits your tastes. It'd be a shame to shell out $2K, then be unsatisfied with the smoke flavor it produces. Most pellet burners who want more smoke flavor, including me, will use one of Todd's smoke tubes to supplement the smoke (I believe also included in the Kitchen Sink Package).
Bottom line is, if you've made up you mind to buy a pellet cooker, I believe you'd be happy with the Rec Tec...it's a good product, and the company has excellent customer service when/if you need it.
Good luck! Let me know if I can assist in any way...
