Price: $75.00
Pros: They work like advertised. Fast dependable service. They have several sizes to choose from to balance your needs of chilling with the right size chiller.
Cons: As with ALL non-servicable chillers. You must take care cleaning and sanitizing or you will ruin beer.
Recommended? Yes

Comments: DudaDiesel has many sizes of heat exchangers. This will allow you to find one that fits all of your criteria. I recommend you take time to read their chart on choosing one. And as for the person who did the review who said they couldn't get a response, I find it hard to believe. I have had several dealings with this company for beer goods and bio-diesel and they are top notch with support for me.
I also have a Blichman unit; I think the Blichman is built a little better, but I'm happier with the price/quality ratio of the DudaDiesel unit.

It doesn't matter which brand you buy, clean clean clean. Then make sure it is sanitized twice over. My Blichman unit is 3 years old with many many brew put through it and little pieces of debri seem to never quit coming out of it when back flushing. I now keep an extra inline filter in front of my plate chillers.

Summary; Buy with confidence.

Comments: I've had this just about a year.
Cools wort down to coolant temperature as fast as I can pump it.

They have different configurations dependant on your set up.
