Polyscience Vs. Vacmaster

I know that this has been discussed many times.
Why pay twice the price or sometimes 3 times for a machine which can do the same things. Sometimes even bigger chambers.
Are there advantages Polyscience models have over the Vacmaster (215c vs the 35xp)
This would be for a catering operation.
Thanks

Pump, programs, "custard cycles" (You can boil/release/boil) , and seal bar(s) I think are the key advantages, that said I'm very happy with my Vacmaster.

The 31 looks more similar in features, the HACCP printer does look neat on the 35xp.

Pumps are the big difference. The more expensive the machine, usually the better pump it will have. Better pumps pull high vacuums and last longer, with Busch pumps being king of the hill. If you have a few hours to kill, the forums at egullet.org contain many hundreds of posts discussing vacuum chambers.

For a catering operation I would get the best vacuum chamber you can afford. Once you start using one, you will use it nonstop. The last thing you want is the machine to go down leading up to an event.

I've spent hours reading the egullet thread. The pump is definitely better, but will it compress melon better? will it seal liquids better?

This is a tough decision. I will be using it every single day for hours at a time. It seems like the MVS need alot less maintenance.
Anyone use both?

@Yitzchok — No, they won't compress melon better. No they won't seal liquids better. That's driven by the pressure you can achieve, and if your patient, all of these pumps can get low enough. But, the pump does matter if you have a lot of sealing to do because they can draw down the pressure much faster. Also, things like how easy a machine is to clean, how easy it is to service the pump, how well made it is matter a lot if you're going to rely on it for production work. Having a machine break in a restaurant, and not having another machine, makes for a very bad day.

@Chris- That being said, the Polysciene model would be the wiser choice for large production. I was looking at the MVS 45XP. For events, I sometimes need to compress 200 3 oz slabs of watermelon.
