I will say this, I have spent the last couple of days learning way more than I ever thought a plumber should about suspension systems, and honestly I still don't know enough. I think that his stuff would have been initially less expensive and cost you far less in the long run at the maintenance level. I compared 6 different manufacturers and quite honestly I bought the best of the 6, I got what I paid for per the time of the transaction. Had I never seen Steve's stuff I would still be bliss fully happy with what I have. Dang, Had I seen the quality of his work at the time I was making these hard comparisons I would have made the run to Arizona and purchased his products hands freakin down. Look real careful and then it becomes blazingly apparent that this guy knows what he is doing as well as cares what he is doing. If you think you do and you think you can save a few bucks take a real long look and compare. I strongly recommend you look at EL Polacko's products before you buy anything. They are by far superior!
