I have a food saver pro It is very very good 5 years old no problems at all. I do around 11 elk and 20 deer a year not counting tons of fish.This was the 1st one I got and bought ot on a deal so I do not know any dif typs.
I use the regular food saver bags you an buy them online pretty cheap or look for a special at your store. Would buy the same one Pro again and they really work well. Don't do the volume ELKINMTCWB does though. Lucky guy
