Happy your own experience was positive, heatherlite.
I don't know why this seller keeps changing her eBay name, clearly it's her choice. I don't think it's a bad idea to search here, sometimes transactions on eBay don't happen for many reasons, and I am always of the view that the more information one has, the better. These are big ticket items, and I also wish the selling feedback were not private, it would give buyers a better idea of their seller.
A prospective buyer can evaluate all the information and make their own decision. Your post about your experience is welcome.
There are numerous reasons why a seller might change their name on Ebay.
Hermes discourages resale, for one. To find out more about "private" sales,
one can always contact the buyer and ask for more information. I have done that several times and gotten the information I needed concerning Hermes handbags. Also, many long standing Hermes resellers use private and their feedback is 100% as well. Maybe it's better to find out why a seller changes their name before implying a negative connotation.
