I don't really have a problem with some sort of progressive/regressive betting system as long as it's done right. Multi-denom machines fit the bill. An example would be the Wendover Nugget where a lot of their machines had 5 cent, 25 cent, 50 cent, $1, $2, $5 denoms all on the same machine....and the payscales were the same on all denoms. Best game was NSUD.
On some of the single line video pokers at the Wendover Peppermill properties you could bet from 1 to 25 coins. Betting 1 to 4 coins you only got 250 for 1 on the royal....but from 5 coins to 25 coins you got 800 for 1 on the royal. Use any kind of progression/regression you want; bet 5 coins, 6 coins, 7 coins, 13 coins, whatever....all the way to 25 coins....then all the way back down to 5 coins, whatever floats your boat. Best game was NSUD.
This is my idea of the way it should be done.
