I just saw this when browsing listings on KSL:



I paid almost three times that for ours new. Of all the baseball crap I've bought, I consider this easily the most worthwhile investment I made. For the life of me, I can't throw two strikes in a row. As long as the balls you're using are relatively homogeneous, this machine will throw consistent strikes at speeds similar or slightly exceeding what they'll usually see in games up to about the 12U age group. Some baseball coaches hate theses machines for some reason but online user reviews are almost all positive.
