I've been flying a friends coupe, 2503H, and it also has a shimmy at around 45-50 mph, always on the landing roll-out. Full up elevator to take the load off of the nosegear helps in every case, and steering left or right slightly also helps. Sounds like somethings worn or loose to me, although I know the wheel has not been balanced.......
