Papillon Owners..help Me?

Lately i’ve been thinking about papillons.
because i took care of my neighbors for a day and my dad (who usually doesnt like dogs)
said that he would like to have one. the one i took care of was perfect.
he was so cute and smart. he was still a puppy and didnt know any tricks but sit, and in 1 day i taught him now to lay down :]
so, i’d like all the ups and downs of owning them.
i already know that they are hyper, sometimes hard to potty train, and not very much like lapdogs (i’ve heard a few people say they are like mini border collies)
do they shed alot? are they very expensive to own? are they really fragile?
aare they OK for first time dog owners, that are researched on the breed and pretty much know what they’re doing?
are they hard to find (like breeders?)
i havent ever owned a dog before. and my dad has said no to most of the breeds i’ve wanted.
but he really liked that papillon, so i want to know if they are good for me ^_^
thanks everyone.
