I never had a rice cooker growing up until I bought the Kmart once when I moved out, and I found it great! Easy to use, cooked rice just fine for my tastes (I'm not fussy) and was of course very cheap. It got damaged in a subsequent move 6 months later and now I'm rice-cooker-less again. I see rice cookers for $100s of dollars, what makes them so much better than the $13 Kmart one that justifies the cost? If I wanted 'the next model up' what would that be and what would I get for it?
I terms of size I really won't need to cook anything more than 2-4 cups of rice at one time so a 6-7 cup model seems fine, 10 is overkill, and at this stage I'm not looking for a fancy multi function device, just cooking rice well is fine. Easy to clean, durability and food safe materials are desired. I only eat rice ~2 times per week so not an everyday thing, but regular enough.
Cheers
Panasonic is a good compromise on Price / Cooked Rice Quality.
