I'm about to order my EGT/Boost gauges. I'm leaning toward the SPA DG-211. I like the idea of 2 gauges in one pod. I also like the looks of the Auto Meter and the Banks, but would have to install a 2 pod system. I just like the looks of the single pod install. I know they install all the same, so it boils down to quality and service.

What do you think of the quality of the 3 brands mentioned?
How about service?
Who has best price? What should I expect to pay?
What is the recommended probe size?

I'm turning to you folks who have much more experience than myself.

Thanks again!
