OfficeMax has a low-end keyboard on sale free after MIR this week. They also have this high end one, though they may not even know it!
On their web site, it is $30.00 with a $5.00 mail in rebate:
In store, the shelf tag lists it as a clearance item for $10.00.
When it scans, it shows up as having a $5.00 instant rebate. A $5.00 mail in rebate is then available in the OfficeMax rebate book for this month. A rebate receipt prints at the register.
The guy at the counter was pretty surprised. Said he was going to get one himself.
OfficeMax in Roseville, CA had about 15 of them in stock.
