“is it safe”
There are always risks in selling on ebay, or anywhere else, but if you follow the systems should be ok. Read up on ebay how things work, HELP AND CONTACT at top of most pages is there to be used, just enter subject and read.
That is an expensive item you are selling, so beware of scammers, and if in any doubt or any unusual requests from buyer come back here for advice.
