My preference is the Remington, though the Mossberg seems nice also. I agree that you should try to buy both, then at some point, you may want to sell one, if you don't like shooting it as much as the other.
The Mossberg may bring about $150-175 on a good day. The Remington might bring closer to $200.
People are like rifles. Some are tried and true, having great eyes, personality, and fun to be with. Others never seem to hit the mark with you. Still others go off half-cocked. Still, it's nice to know most of them.
