OK, I'm planning to buy either one of these ball machines. Unfortunately where I live (Europe), the choice pretty much comes down to these 2 models. I have seen the features and they look pretty similar: same max speed (135 km/h), same drills more or less (on program), the only visible difference is that the Tutor Tower weights 8 kg more... a tank. There's also the Portable Spin machine by Wilson but it doesn't excite me as much (even though it's more portable and lighter). So... what would you suggest? The Shotmaker Deluxe is pretty much a standard I know, but is a tad pricey, the Tower less expensive. People who have had experience with one of those or both? Thanks for any kind of input.
