I have a FoodSaver and it works fine. They seem to have a hundred different versions of it that all do roughly the same thing.  The only pain in the butt for me is storing it. So, based on your kitchen setup and storage space, choose the one that is the easiest to deal with in that regard.  The version I have has space inside to store/cut rolls of bag material. That is a waste of space in my case.  I'd rather have a smaller unit and just buy the pre-cut bags on Amazon.  Although, it is nice to have the cutter on the machine.

I don't Sous Vide but I do freeze of course.  Not always a perfect outcome but much better than trying to do it with zip lock bags.

for the marinade you can always go with the ziplocks. i went with the ss cabelas vacuum sealer last time, i was only getting about a year with the cheaper foodsavers

I've had a foodsaver for about a year. I'm with @KiterTodd in that all the foodsaver models are about the same - just pick one. As far as sealing items that are wet: 1) I've never sealed a liquid or anything with a liquid marinade 2) for items that have "some" liquid - I just seal right before it sucks the liquid from the bag. It's not a tight vacuum, but it works well enough for me. I understand some folks refrigerate or freeze items before sealing to reduce the problem of pulling liquid from the bag.
I'm no authority - I'm just offering what works for me for the sake of conversation. Also - this is one of the best purchases I have made. I wondered if I would use it much, now I wonder how I lived without it.

I kept hearing people say that (the "year" thing), so I got a Weston. They make the Cabelas vac sealer (or did then, don't know about now). I've had it for a good 6-7 years and it has never failed. It was NOT $54! 

@Photo Egg bought a nice looking one a few months back. I think it was a VacMaster. I remember thinking I would probably have liked it better than mine, though I don't remember why. I think it was feature-related. Maybe he'll chime in. His was not $54 either. 

I disagree that all food savers are the same. I have one with the auto seal and it sucks. Get a flat manual version and you’ll have a lot more control and you’ll save bag material.

I'd say the suckier the better, eh ?
