Hello there,
 I have used a VIP of one generation or another for a lot of years, and can 
find no unkind words to say about them. The are the steady eddy in all the 
labs I have worked in over the years. You can't go wrong with them.
Performing routine cleaning and maintenance on them is important and they 
will give you faithful service for years.
I have worked in labs having 6 units and currently have three, in two 
different generations, that are the workhorses for our lab. We process about 
40,00 specimens annually.
Good luck on your demo, I don't see how you can go wrong.
