Google started the process of making routers easier to use and more cylindrical with the $200 TP-Link OnHub. The company then partnered with Asus to produce a second model costing $220. The design is slightly narrower, and you can wave a hand over the top to instantly prioritize a device.
Since that extra $20 bucks might be just enough to dissuade some of you from picking up the latter option, a couple of retailers have evened out the prices. Right now Best Buy is selling the Asus OnHub for $199.99. If you don't want to bother with the main site, you can go through eBay instead.
B&H manages to undercut that price by four whole cents. There you can get the router for $199.95. It's also showing me no sales tax, which is roughly $10 less than Best Buy.
Whichever site you choose, shipping is free.
