That ridiculous picture of mine has two Humanscale M/Flex dual monitor arms and a Humanscale M8 holding up the laptop. All of which talk to a 4x2 KVM. It's a ridiculous setup. But hot diggity damn is it lush. I inflicted dual monitors on an M/Flex on the receptionists at the birth center. They love it. Remember: buy used. Daytraders, Bloombergers and techbros are big into Humanscale so they buy them, blow themselves up and their shit gets swept up by vultures who promptly post it on eBay. They're like Aeron chairs in the dot com era except any schlub can sit in a chair. Monitor arms? Those require, like, a screwdriver.
Ebay is a whole order of magnitude cheaper than Amazon. Used it is. You've done your receptionists a huge service. I've pestered every single one of my desktop-using roommates to get dual monitors. No one comes back to single monitors from two. Yah, that set up is a dream. The TV monitor to top it off is [rainbow barf]. BUT, how the heck are you and veen gucci with no floor padding to protect the wood from wheel scuffs/scratches?
