I've got a brand new IConcepts IR keyboard for the 300. I bought it just before I upgraded to the 600 and it does not work with the 600 so I have no real use for it. I tried every IR keyboards for the 300 including the Targus, Belkin, MicroInovation and found the Iconcept the best. It is the closest to a regular keyboard with 5 rows of keys. The space bar is the best of the bunch. $35 plus $5 shipping. I have photos. PM or e-mail me if interested.
