For 200 bucks I have the ATEC hitting streak that uses solid "soft" but hard balls, can be used inside and out and has held up for 4 years already. Throws about 53 MPH, but move it closer to home to simulate faster. The best part is the solidness of the balls vs. the floater softer types. Outside of the big dollar machines, this one works for us... Came with 4 balls and we purchased 15 more...
