The Harbor Freight store in town has a red, AC powered vacuum pump by Central 
Pneumatic on sale for ten bucks, marked down from 15. It's used to pull 
vacuum on air conditioning lines prior to adding refrigerant,  ad copy only sez 
"it 
will pull a full vacuum within 2 minutes. at 4.2CFM ..."

It seems very uncomplicated, no mention of  a regulator or anything... is 
this of any practical use to me should I decide to get into bagging wings and 
stuff? If yes, I would probably just buy it now and store it until I got the 
urge 
to try and make bagged wings down the road, but is this type of unit really 
any use for our applications, esp. for a raw beginner at bagging? Or should i 
wait and maybe buy a complete package later if the mood strikes? Money is 
ALWAYS a factor...
