I recently moved to a place with a tennis court. Problem is, I don't play tennis and don't really have anyone to play with yet. I used to have a tennis training aid when I was little, that I thought might be good practice for me now. It had a piece of heavy rubber for a base, roughly 1x1 foot and maybe 4 inches high, with a long elastic rubber string attached to the top. The other side of the elastic string had a tennis ball attached to it. It was basically so you could play and practice tennis by yourself. It waasn't 100% realistic, but it was a lot of fun. I didn't even play tennis back then, I just hit this thing all the time because it was fun. So, now I've been looking for something like this online, with no luck so far. Does anyone here know where I could find one? I don't really know where to look, or even what they're called. The tennis training aids I found were nothing like what I'm looking for. I'd appreciate the help a lot.
