Costco usually has a nice Foodsaver for around $100-120. If you have a membership, try it out and see what you think. We have whatever one they stocked last year and it is not bad. My biggest complaint is that the bags are not resealable, which is nice for stuff like cheeses and slab bacon. Other than that, it does what it should. Bags have never lost their seal and it has good suction.
I tried the Ziploc one and it didn't do it for me. I found the seals failing more often than I would like. Reynolds use to make one that was fickle, but was awesome once you got used to it. The bags were resealable and relatively cheap. They discontinued it because of poor sales, so, last time I checked, the bags were going for several dollars each on ebay.
