I bought a typeheaven on eBay. My first impressions is that it's just a worse realforce. They feel about the same switch wise. I don't notice a huge difference between the keys on the typeheaven and the realforce. The keycaps are awful. They don't sound that terrible, not the worst sound, but not as nice as the pbt caps, but they're sandpaper. They are very rough, some of the roughest I've ever used. If I swapped the caps on a realforce on, it's probably feel almost identical but at that point you've already exceed the price of the realforce. If you want a full size Topre board, get the 104u.
