Attack! But please one unit per person! The demand is so high, be nice with others!To buy it click here please.[Copy/Paste Update]:Also note that FMA XY is $43, the Z sensor wasanother $25, and the cable wasn't included. So that was at least $75with cables. Also, we have to pay a royalty to FMA and don't buy partsat the same volume they do. Plus, of course, FMA doesn't make the Z atall anymore.You might also want to note that our sensors are less than thePaparazzi ones ($125:http://ppzuav.com/osc/catalog/product_info.php?cPath=13_5&products_id=66&osCsid=08841e8ba7cd41f6d279d30be5167e22)and the same price as AttoPilot. Or you can make your own, just buy the 6 thermophiles for about hundred dollars from Digikey (http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=MLX90247ESF-DSA-ND). So basically these are tied for thecheapest full XYZ sensor solution in the world.However, if people want to wait for FMA to bring the XYs back instock, people can always buy two of them and use one as a Z sensor andsave a few dollars. (just ignore one wire).
