My son did numerous Showcases Showball (son got one invite for a school visit out of this showcase), Baseball Factory , Blue-Grey (Major waste of time and money) and a couple of College camps. By far the best money spent (for my son) was going to a College camp. He went to two camps, both schools have made it to the Super Regionals and funning enough are playing each other. The one was a waste of money, it was a glorified babysitting summer camp. The other was run like a camp should be. The morning was for teaching and learning and the afternoon was the same with a game thrown in.
To make a long story short after the one camp both the head coach and the asst. commented to my son that they really liked him but they felt he was a year behind, being from the Northeast. They were honest with him in saying that if they signed him he would only get 10-15 AB's over his first 2 seasons and they would rather see him go play for 2 years and get a few hundred more AB's under his belt and if all goes well transfer to this school. No promises were made on this and my son knows he has to work hard for this to happen, which is exactly how he wants it. These coaches called many JUCOS on my sons behalf and he ended up signing with one of them.
