I got mine online .....
www.dropcam.com
But have since found they are available at Best Buy.
I don't think "shopping around" for this will yield a better price -- seems they have the "Apple" mentality of holding pricing firm regardless of channel of distribution. Amazon pricing was the same.
there are only two models -- "Pro" roughly $199 & standard roughly $149
to save you time --Major differences between two are
Field of Vision 130 deg vs. 107 (not a big deal)
Zoom: 8x vs. 4x (another not a big deal)
Pro (supposedly) has better night vision -- from experience, our "Pro" is EXCELLANT at night vision
I do not believe STD has motion or sound email alert capability
I do not believe the Standard has any Audio capability and the "Pro" WiFi connection is supposedly (??) better
