Depends.
For one, barely anyone has a record player. However, some people might want it as a collector's item. Even with that said, do you feel that you are "big" enough for a fair amount of people to want to buy it?
IMO, its not a very smart move in terms of making a profit. I dont know how much it costs to press up vinyl, but the fact that you may only sell like 20-30 of those says something.
