Rhino, there's a difference between classifieds vendors and forum sponsors. A classifieds vendor could be almost anyone. A classifieds vendor may be just fine, but when it comes to shopping around, there are two classes of dealers that are at the top. Forum sponsors and knowledgeable local dealers.
Forum sponsors sponsor these forums. They have nowhere to hide. And to be financially able to be a sponsor, they have to be big enough that they've got some serious investment in doing their business. For an incompetent dealer, becoming a forum sponsor risks the death of their business because a fish in a fishbowl is the fish everyone gets their shot at saying it's ugly.
I am not saying that forum sponsors never screw up. I personally screw up, everyone here does, and so do the finest businesses in town. A good business doesn't make major screwups very often, and when they do, they try to get it fixed. A forum sponsor is spending money to get more business, and by doing so they're exposing themselves to complaints on the very forum they sponsor, even if the complaint isn't justified.
I work for a manufacturer. Been in the biz for several decades now. I have some perspective on this stuff. And here's my opinion.
The two best kinds of dealers there are, are forum sponsors, and a local knowledgeable mom & pop dealer. Both classes of dealers have no place to hide: they do business in a fishbowl where all the cats in the neighborhood can watch. And although they may not always be able to beat the supposed price of some other kind of dealer, with a forum sponsor or a local knowledgeable mom & pop dealer, you are paying for value added. In both cases part of that value is confidence in the bona fides of the dealer. The local dealer adds face-to-face value, there's knowledge of what works well in their area and you have a personal relationship. The forum sponsor adds value by sponsoring the forum where you're learning about metal detecting, and forum sponsors usually have economies of scale that permit them to stock a wide variety of product.
Local dealers are dying out because of Internet sales competition, and that's sad. The local dealer's price might be 10% higher, but that 10% is almost nothing compared to bigger picture of the value a good local dealer can add. Shopping for the lowest price tag without considering value added is not a smart strategy.
I'm not criticizing the forum sponsors who do most of their business over the Internet. They, too, have their value to add, and it's different kind of value. The industry needs both things to be healthy.
Please notice that I have said nothing about what brand is better than another, or even whether to buy new or refurb/demo or used (both local dealers and forum sponsors have that flexibility). What I am saying is that there are two kinds of dealers you should prefer to do business with-- forum sponsors, and knowledgeable local dealers. There's always the risk that something may not go quite right, but with those two classes of dealers the risk is low and the chances of satisfactory resolution are high.
