This question comes up all the time on the forum. From my experience on the forum, asking the brethren what cooker to buy is like asking what car to buy on a car forum. There are so many good ones out there.
I would pick one, or maybe a couple out, and ask the brethren their experiences with those units. Find out the pros and cons of of those particular units.
Check out the suggestions on here, narrow your options, then run those options by the brethren. IMO, you will get more usable information.
