I have the basic model found at target. I got it about a month ago, dont remember the exact cost but I think it was somewhere around $55-65. Also got the jar sealer attachment and about 4 dozen jars divided amongst quart, pint & half, and pint sized.

I loaded up on these bags: Commercial Bargains 2 Pack 11" x 50' and 8" x 50'

The 8" perfectly fit my burritos. I'd say I'm using about 6 inches per burrito so if I'm careful I'll get at least 100 burritos out of a $12 roll. Also you can use regular ziploc freezer if you trim off their zip lock seal. The vacuum doesn't agree with the thin ziploc bags every time but it's surely good enough for freezer burritos.
