Sorry for my long absence from the board. Summer, if you haven't bought one yet, I have the PRO2300 on a special through Sunday night (5/13). You can find it here - http://www.qualitymatters.com/dealoftheday.asp
This is one of the best suction style vacuum sealers out there but for the volume you are doing, it might be a good idea to move up to a chamber sealer of some type. A good intro level machine is the VacMaster VP112 Chamber Vacuum Sealer
. With a chamber sealer, you don't have to worry about the juice coming out of the bag, in fact you can seal liquids in it if you want. The only limitation to this machine is that you can't seal up the heavy canning retort pouches. For that you would have to move up to the next level of machine, but only a few people have the canning expertise to can with retorts.
If you want to take a look at the VP112 you can see it here - http://www.qualitymatters.com/VacMas...qmar-vp112.htm
