I have used the search feature, and found a poll that puts the Johnson, Ranco, Helix, and Herpstat up against eachother...but that's kind of a mixed poll because 2 are proportional and 2 aren't.

I am ordering either a Ranco or a Johnson tomorrow and don't know the difference, and more importantly would like to know which one people are finding more reliable and why...

Thanks for any help you can provide.
