I am shopping Chamber Vacuum sealers....

I need the capacity to do a whole chicken

And dose it make a big difference between an oil-less pump and an oil type pump ?

Can anyone guide me into what will work best ?

Bought mine at costco, lem but lower cost. Oil pump

That's what I was thinking.... will it do a whole chicken ? Have you had any problems with oil leaking from the pump ?

Bingo...and no leaks

U get a bag long enough u can bag a rifle...

I have not tried it, has a ramp to prevent liquids from leaking. If that is out a chicken should fit . No oil leakage
