I'd like to buy a display for my pi (B+, I will by it as fast I can). But I can't find any options that does not require assembling. Display can be "anything", like character lcd (http://www.adafruit.com/product/399), small (touch)screen (http://www.adafruit.com/products/1601) or led matrix (https://learn.adafruit.com/connecting-a-16x32-rgb-led-matrix-panel-to-a-raspberry-pi/overview).
It can be connected via hdmi, gpio or usb, but it have to be possible to control it via command line.
And power supply must be micro usb or pi itself. It's nice if it's cost under 50€ (70$).
