For me it was the Glove80 -- it is kind of mid-range pricewise in this space (but still around $400), but it immediately solved my RSI pain and they offer a ton of accessories like quick release mounts you can use to set each side up on a chair arm for example. I debated getting something like the Freestyle 2, but I had a suspicion the the curvature following the shape of your hand was going to be a key feature, and I think I was right. No regrets.
