I've got an older 16.5 foot Wooldridge Plus model sled with a 115 Merc outboard jet. It's an old one and cost me less than you're looking to spend. It has a great top, side curtains, and rear drop curtain. Though only 16.5 feet, it comfortably fishes 4 people--it's got a snub-nosed front end so it's got the room of a 19 foot boat. I run it in the Columbia primarily, but it turns on a dime and runs very, very shallow. I absolutely love this boat! My only complaint is that I do get the hell beat out of me when the water is rough. That's the downside to a sled. But it will go anywhere and take a beating. From the info you've provided, it sounds like you could use a similar boat. Now, if you could just find one.... :p
