I've been seriously looking into getting a Raspberry Pi 2 B setup. Here's the problem:

Amazon's Pi2B "Canna Kit" offers everything in this drop, PRIME shipping, for $70. With the shipping here, Massdrop is actually a bit more expensive (and you have to wait for the drop).

Ada Fruit is the "go-to" for robot makers, embedded hobbiests, etc. You'll probably pay $5-$10 more for the same setup here, but they have more options (different kinds of enclosures, WiFi modules, etc.). They also have a MUCH wider selection of screens and touchscreens, with their TFT touchscreen running about $5 more than the $30 one here—and the nicer capacitive touch screens for $45. There's also some reasonably priced mouse and keyboard setups, cheap USB audio interfaces of better quality than the onboard audio, camera modules, etc. In other words, a one-stop-shop for many of the interesting things you might want to DO with this unit.
