Iron Mike - I've always thought these were for full time indoor failities as they aren't real mobile....
Might want to search for a 'wheeled" machine - Jugs, Bata, Atec... Used maybe a good option - BBFAM might sell you his?
As for the need: obviously personal preference...
We have a cage, machine, tees, auto feeders and balls.... right next to the half-pipe, horse shoe pit and coolers.... Have FUN - numero uno!!!
I also have three kids ages 9-15, all of whom play the heck out of the game, baseball and softball... We use this equipment all the time...
I've never felt that if my kids didn't receive D1 scholarships that all this stuff would have been a waste of money - I'll resell it when their done or maybe use it for grandkids (LORD HAVE MERCY - I'm way to YOUNG for THE "g" word....)!
To go along with all of the equipment you do need SOLID mechanics - TEE WORK!!!! NO DOUBT!
