I just went through the same thing. I have a bunch of on/off toggle switches though. Ordered a few GE toggle switches ($39) and dimmers ($39) as well as some [Zooz on/off toggle switches( $25)] (http://www.thesmartesthouse.com/products/2-zooz-z-wave-plus-on-off-toggle-switch-zen23-2-pack) and dimmers ($25). The Zooz switches look similar to the GE, but the GE has a nice tactile feedback when you click the switch that I like. The GE also comes with a white/neutral jumper that is required (you need to make your own with the Zooz). The Zooz are Z-Wave Plus which is nice and they are a lot cheaper, so I went with more of those for the rest of the house, even though I like the feel of the GE better. The Zooz (and maybe the GE, don’t recall) need to have short srews when you screw in the wall plate as the screws actually go into the body of the switch. Both switches stand out a bit from the wall, making the wall plate stick off the wall a bit. I had to shave down the screw holes in the wall plate so it would sit flush against the wall.
I was looking for a outlets that had an LED so I knew when it was on as well as an obvious button, so it can be easily turned on and off physically. I bought a GE Receptacle Outlet ($37), Enerwave Receptacle Outlet ($37), and a Linear/GoControl Receptacle Outlet ($34). I like the GE one the best, but it isn’t Tamper Resistant. The Enerwave is similar to the GE but has Tamper Resistant so will go with those from now one. I bought the GoControl thinking it was Z-Wave Plus, but it’s just regular Z-Wave.
Note that most of these switches and outlets do not come with wall plates or hardware. I bought a bunch of these $0.65 wall plates as they fit the paddle style switches as well as the Z-Wave receptacle outlets. They also come with the short screws required by the switches.
