Spratley, journey, marlon, and lowe cover the vast majority of jon boats currently sold that are used by the trout guys. Marlons are very thin and light, too thin in my opinion. Lowes are riveted and quite popular.
If you want welded you will likely be choosing between a spratley and journey, you can't go wrong with either choice.
