IMO the best combo I have used is the Schurr Profi II paddles with the CMOS 4 Keyer from Idiom Press. Near perfection and less pricey than the Mercury knock-offs now available from various sources. The Schurr does not move on the desk what so ever. The CMOS 4 is an elegant keyer. Cannot be beat for effortless sending. 73 de N1LQ-Dave
