I almost bought a MN40 or MN45 a while back.Yeah, actually hasn't changed much I guess. I have their metal axles and 4-link bars on my WPL truck. They can be turned into some pretty good looking little scalers.
Or the WPL Landcruisers
They just seem a bit ..... toy grade I guess. Somewhere between toy and hobby grade. Correct me if I'm wrong as I've never had one.
