So I recently got one of these: http://elitekeyboards.com/products.php?sub=topre_keyboards,rf104&pid=yk2100 and promised to review it after a few days. It's now been a few weeks so I'm ready. I've been using a standard Realforce 104 before this.
Like all Realforce keyboards (aside from the Type Heaven which I haven't tried) this thing is built like a tank.
