Actually there are some versions of it that aren't too pricy - go to http://www.usplastic.com, click on the "More Tygon Tubing" link and look at the prices for the various "Beverage, Food, and Dairy" tubing. However, the down side is that it isn't anywhere near as flexible as that made for the "Peristaltic Pump" application (instead of a Shore A of 40, the beverage has a Shore A of 65, still better than vinyl, but not as good as some of the silicone).

DG - here is a page with Vinyl tubing, shows a Shore A rating of 80. So from that regard some of the Tygon is much, much closer to silicone than vinyl. Just be careful that you look at the Shore rating of the actual tubing you use, as there are different grades of tubing. Also, the softer stuff doesn't hold up to as much pressure for a given wall thickness.
