No. I did check Amazon.com and eBay and saw a QX5 for about US$75 after shipping costs: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=380262406989&rvr_id=139147359954&crlp=1_263602_263622&UA=L*F%3F&GUID=0b3b537412b0a0e203e63006ff9becb0&itemid=380262406989&ff4=263602_263622 I'm not sure if I want to buy one at that price, since I already have a QX3.
