I've had my eyes on the Silent Partner LITE for a few years now and think I'm finally going to make the investment in one soon. I've owned a ball machine before (Tennis Tutor Jr.), so I know all the positives and negatives in owning a ball machine. My question is this: Is there an ideal time to purchase one? I see they're on sale right now ($699 as opposed to their regular price of $799), but do they run better sales at any other time(s) of the year? I don't mind waiting for a little while to save even more money. Thanks in advance for any advice.
