The Ketboard Company has a "USA Topre Realforce 86UB 45g Mini Black on Black Keyboard". Other than the extra windows key, and the larger spacebar, I believe it is the same as the 87UB. Is the spacebar, like the 103 series, difficult to replace (if need be)? Also their price for the 86 series is the same as the 87 series. Isn't the 87 series newer?
Thanks
