^The NEX is available in grey market but is priced at 27k,which is quite high,even if its launched officially it shouldn't cost more then 27k,but since it isn't launched grey market dealers are charging a premium.
They stack up quite well and is the one of the hottest selling cameras like in tech savvy county japan it outsells the combined sales of all the M4/3 cameras from panasonic and olympus.
The only drawback at the moment is the lack of lenses like prime,macro which will be launched in 2011,but if you don't mind bigger size lenses you can use the Sony SAM/SSM lenses with optional telecoverter or you can get a cheap $50 converters and virtually use any lens out there from canon,nikon,tamron etc but with manual controls.
