That is weird, coz you can pay him thru paypal on ebay anyways, what's the big deal? if it's an ebay listing methinks he's trying to get away from some fees he has to pay but then that's not right, if you go thru with it thru ebay-paypal checkout you at least have to areas to claim there - it is an ebay official listed item and paid thru secure paypal system... if he asks you to pay outside next thing he might say is put in send money option as "gift" and I dont know if you can claim for youe item if he does a runner since it's a "gift" means there's no item involved so be wary.
