OK I am deciding between the Samson Powerflow III 2 into 1 or the Cobra PowerPro HP 2 into 1. Has anyone had any experience with these that could provide any input. I am looking for a deep rumble that is loud but not obnoxious. I am looking at quality as far as rust, discoloring etc... Performance is least on my list. So if you can provide any input from your experiences I would greatly appreciate it. I wish I could find these locally so I could listen to them in person but I haven't been able to locate any.

 

Cobra has a great warranty and product support. I've read Sampson is almost invisible once the sale is made.
