Pontoon shopping at Chicago boat show

[liledgy]

My sibling and I our looking to replace our 24' foot party barge with a smaller pontoon. 18-20', 4 stroke motor, composite floor, etc. I know bennington is a good brand, can others here name a few other good quality co.'s? It will just be for cruising, I would think a 50 hp would be enough (maybe). Any motors to avoid? Other options? Thanks for the replys.
