Well Raffle.com seems to be a 403. Raffling used as a verb without an object as in 'to take part in a raffle' would work better than using Raffling as a verb used with an object ie; 'Raffling off a car', the former is generic and covers all objects. Either way the name is only worth the amount of effort put into Developing the name (website). As is, without development, $500 - $2000.
Rafflings however is a whole different animal.
