On the flip-side, I have a OE backrest ready to ship if anybody is interested...
Make sure it's in the classifieds section here...the OE backrests and flyscreens are hot commodities....shouldn't have much trouble getting rid of it.
With ebay....it's feedback feedback feedback. If someone has less than 98% positive, steer clear. Unless it's a totally one-off item you absolutely can't get anywhere else, chances are there's another seller with the same item who is more reliable. And just don't go by the number...open up the page and skim through the comments for the past few weeks. More than once a seller may have a high feedback number and good percentage (98-99%), but reading the comments reveals that just recently they're started getting lots of neutral or neg's...so the business started folding, or there's someone new doing the ebay who doesn't have a clue, or something like that. Often, people leave + ratings, but include notes like "item OK, but really slow shipping", so if getting it fast is an issue, again steer clear. When I bought my ZX14 r/r off ebay, the seller didn't list the shipping service "standard shipping", charged like $25 to mail a small, light item, and ended up shipping it "fedex smart post" aka super snail mail. Took nearly 3 weeks for it to travel literally about 100 miles....
In ebay's push to make it more "accessible" for casual internet shoppers, the buyer protection programs make it a lot easier to hold flake sellers accountable, and probably 90% of the time disputes favor the buyer. Unfortunately, scammers take advantage of that with legitimate sellers, claiming they didn't get the item, intentionally breaking it, then claiming it arrived like that, ect.
Ebay also expects sellers to leave + feedback for buyers the instant they receive payment. (Sellers can't leave neutral or neg...positive or none). More than once I've left some generic + comment for a buyer, then they try pulling some bullshit telling me the item was broken or damaged, or demanding a refund for shipping because they claim it arrived late or something.
