Wow, not to bash anybody here, but before you discount Kellyco based on one item or "I heard stories about..." I have made four purchases from them in the last five months with only one very minor problem. I received my orders within three days of placing them, and all but one were shipped free. In every case the prices listed on their web site were identical to everybody else. Say what you will about their package deals, but in both cases where I bought detectors the price was the same for the detectors as it was on everyone else's web site. No additional charges for the extras. Free is free.
I'm not bashing the forum sponsors, but for me, I don't have time to make six or seven phone calls simply to save a few bucks. It's more convenient to open a couple tabs in a browser to compare side by side the packages and pricing than spend a couple hours playing Let's Make a Deal on the phone or through multiple emails or PMs.
I'm not saying buy from kellyco, or don't buy from Bart or Steve or any of the other dealers. All I'm saying is don't let a couple bashes discourage you from looking at all your options.
