500 for a blade? I have been looking for a used one for the last 4-5 months and the only ones I see that are 500 bucks are pretty old and rusty. Where are you seeing these blades? I found a dealer 1.5hrs from me who has a RB1684 in stock for like $1400. My two dealers that are a little closer don't have any but quoted me the same price.Yeah it doesn't lol. From my experience and what I'm seeing is look for a solid or heavy frame and thick or reinforced blade. Mn, IA, IL are all about the same for equipment types and equipment for what I'm seeing 500.00 can get you a nice hd blade. If something looks cheap or in the weeds there's a reason why it's there.
