My son came up through the Arsenal system, IMO you're not going to find a better program in the Northeast. As mentioned before, Joe and Bob Barth are highly respected in the amauter baseball world and Bob is very well connected to colleges at all levels.
As for the cost for tryouts I understand this is pretty common practice these days so I wouldn't let that hold you back.
Looking back, my son's Arsenal days provided some of our best baseball memories. I'm sure you'll find some out there that didn't have as good of an experience as we did but I'd certainly do it all over again. Good luck!
