Questions about using audiogon to sell 1st time

I’ve read over all material I could find and looked up forums on the matter etc, but thought I’d also ask here just to get more info and clarification. Is PayPal required? I honestly have never used PayPal when I sell my expensive stuff every 4-5 years for upgrades.....but all I could find is yes it’s mandatory....which is awful as absolutely 0 seller protection and buyers use it as a rental service. 2nd how long does an ad last since were paying to place it on site I would assume a few months, but idk. Lastly, is worth selling something on audiogon if it’s only 2200$ or so or would u only sell the higher priced items here bc of the audio community? Sorry for all the questions but I wanted to acquire more info and clarification on all these matters before I place an ad, I’ve had absolutely 0 luck elsewhere which is strange as b&w d3 series maintains its value...which is why I’m looking at audiogon as my last alternative.

thsnks and I hope I can get the info I need, will be placing an ad on audiogon most likely tomorrow once i get some more info.
