Nothing new yet, I've been searching for different items online that have that thrusting motion, but nothing within a decent price range (under $150 for just that item). I think the mixer is the cheapest, but it doesn't have that long of a stroke length. I'm not giving up, so I'll keep you posted. Also, if I find something that I think will work, I'll take pix of how I put it together, to help out everyone else, cuz I know sometimes directions are a pain in the ass.
