i actually dabbled in selling totron lights when they were the first competitor to rigid. basically you get them shipped direct to you from totron. i had to order a certain amount to even get them to ship to me some samples. part of the deal was no ebay, no amazon, no group bys. i ended up using a few on my various rigs, and selling the rest to my friends for my cost.
idk if the no ebay/amz thing has changed. not saying i couldn't have easily gotten away with selling them on amazon or ebay. i just didnt want the hassle of doing it at all. plus, the sellers on the forums ended up getting real competitive and in order to make money, i would have had to buy in vry large quantities, and the profit margin wasnt all that great.
back to the real question though... i trust forum vendors way more than amazon or ebay faceless/nameless folk. amazon/ebay could sell mictuning products as totron quite easily, and youd never know the wiser. a forum vendor would get called out pretty quickly. but yeah... a forum vendor could definitely screw me over... but if you go to the amazon links, and look at the sellers, and then look at what they are selling... lots of times they have a few items that are labeled as totron, that totron doesnt even seem to have on their website.
