I am looking into ordering a pro-tech 600 but would like to hear some of your personal experinces with this item. Example: If you own one would you buy it again? Have you used one in the past and switched to another manufacturer for some reason? Is the quality substandard or do you think this is the best buy for the value. In the past I looked at the pro-tech 48 solenoid activator but I bought the tempo 24b. The reason was not that I did not like the pro-tech, I just got a good deal from my supplier. Any information would be helpful, thanks. irrig8r, I saw in another trend that you got a pro-tech about 2 weeks ago, how do you like it?
