Daniel:
The Leviton 600 watt model number is 16383. We offer this swtich for $79.95. We also offer the PCS version of this switch (also 600 watt) for $89.85 (the one with the programmable soft start duration).
The SwitchLinc by SmartLinc is a brand new switch. The company is now filling back orders that have been standing for over a year. Even though the switch has made it through beta testing after some bug fixes, it does not have the track record that Leviton and PCS have. Unless you really need the SmartLinc feature where the switch sends an X-10 command when turned on at the switch, I recommend (for now) that customers purchase either the Leviton or PCS switches which have proven to be reliable.
About SmartHome's part numbers. They replace the actual model numbers with their own part numbers to discourage price shopping (IMO).
