ziplock freezer bags work great, maybe you could do a comparison of the difference in price between them and a vacuum sealer.
here's a good emthod for freezerbags from www.baitshopboyz.com
If you do not have a vacuum sealer, you can achieve excellent results by packaging cuts, steaks, cubes or ground meat into zip-lock plastic freezer bags. Fill bag with desired amount of meat (quart sized bags are perfect for 1-, 1-1/2- or 2-pound packages). Be sure to eliminate air by immersing bag almost to its top in a sinkful of cold water. Take care not to allow water into the package. The pressure of the water pushes the air out, and by the time the bag is sunk to the level of the zip-lock, it will be as good as using any vacuum sealer. Seal the bag while it is still in the water. Wrap bag in freezer paper, either flat or folded in half, depending on the amount of meat and/or your preference. The freezer paper protects the zip-lock bag from ripping or puncturing, which could open the meat to freezer burn.
