I'll answer - the same number of people would have access to them. Either you are a felon, and are not legally allowed to purchase one, or you are not a felon, and you have the legal access to purchase one, if you desire to do so.
The price is of guns is controlled by the free market, not government regulations. When people weren't buying them in droves like they currently are, the price was lower. The price jumped up when speculators started buying them, thinking that they might be banned. This isn't just happening now, it happened when the 1994 ban was passed as well.
Price really isn't a limitation though, when it is between $500-$2000. If someone wants something enough to prioritize it, they will generally choose to do without other items in order to get it. It might mean eating out less, not having that morning cup of coffee, etc, but if they want it, they will find a way to purchase it.
