Good original product from Amazon.

Top. Have apparently an original Type B get the video jack is yellow (apparently a sign of an original product). Lately here accumulate unfortunately negative reviews, since everyone can produce the type B and LT the reviews many non-functional boards are shipped from China.. I've ordered directly from Amazon ("Ships from and sold by Amazon") and am very satisfied.

Tips: try several SD cards to try out different Images (Raspbian, Raspbmc, OpenELEC, ...). For example, I can on one of my SD cards only boot Noobs, a direct OpenELEC Image not boot. In the line config.txt "boot_delay = 1" Add, if only the red LED lights and the Raspberry does not boot. Powerful and good power supplies use (I use eg Rydges 2000mAh). Possibly WLAN sticks with an external antenna at greater distances than a few feet to the router - indeed need more power but better range. The small sticks take up little space and little power, good at small distances.

Have fun with the Raspberry!
