Both Zojirushi and Panasonic are the best. This one does 2lb loaves: https://www.amazon.com/Zojirushi-BB-CEC20-Supreme-2-Pound-Loaf-Breadmaker/dp/B002XVUAOU/

But if you're on a budget, most brands are good. A rule of the thumb is to look at the thickness and weight of the bread pan. It should have a nice heft to it. Cheap machines will cheap out on the amount of material used in the pan, which will give you uneven heating.
