Yes, it was a little more $$$, but it works great, runs cool, no problems.

(I -think- I bought the "one in the middle" -- getting old, can't remember!)
But again, from what I've read from others, the cheapie "converter plugs" can get you up-and-running.
If you watch the 36-minute video that was in my earlier posting, it gives a very nice overview of the z21 and getting it running. I can't see why anyone would want one of the old-fashioned "push-button" controllers after using this, but that's my opinion only.
My advice (if you want the z21):
- order the z21 "white" from the ebay link I provided.
- order the companion TP link modem from Streamlined Backshop (also the link I provided)
- buy a power supply for the TP link router on ebay (I need to get the part number, I did some searching)
- get the "powerstream" power supply for the z21
here's a pic:
"If you are using the z21 white box version, how are you supplying the the correct voltage to power the unit? Since we have to use 110v in the US and the 2 round pins on the German power block is 220V, will the unit get enough power if we just use an adapter to convert the 2 round pin to a US 2 blade plug?"
I had to do some research when I was putting it all together.
I believe the power supplies that come with the z21 can be plugged into 110v mains, BUT, you need a clunky "2-prong" adapter. These can be bought cheaply on ebay for a few dollars. I bought some, but they make the power blocks "stick out" from the outlet. Just didn't impress me.
So... I bought my own power supplies.
For the TP link modem, you can find the appropriate 110v power supply on ebay for about $6-8.
For the z21 unit itself, I spend about $37 and bought a dedicated power supply that has switchable dc voltage outputs and it has a USB charging plug as well.
