    Default dead pixel? dust spot?

    ok so ive had my nikon d40 for about 3 months now and yesterday i started taking pics and noticed that there was this spot in the same exact spot on all my pictures?
    so i thought it could be a dead pixel..
    so today i take it to wolf camera...(where i bought it) and they said it was more likely a dust spot and it just needs to be cleaned so before i give it to them for $65 to clean i thought id see what you guys think it is? and will cleaning it help?
    the spot is on the middle on the right hand side..
    thanks

    couple sample pics

    Looks like it just needs to be cleaned in my opinion.

    It's dust on the sensor, take a turkey baster and blow air on the sensor. DO NOT USE YOUR MOUTH nor should you use compressed ai as it is too powerful. Just put your camera on sensor cleaning mode, th emirror shoulf flip out of the way, and the shutter open, with the lens removed, and the front of the camera facing down rise the turkey baser up into the amer (do not touch the sensor) and blow a few burst of air thoroughly around the sensor. Then, keeping the camera facing down, turn it off and let themirror and shutter close. then replace the lens.

    no it isn't the lens it's the sensor.



    dust on the lens won't show up as the dust is out of the focus range, and is so superimposed by light it has no effect. However dust directly above the photosites casts a shadow on them and makes those dark sports.
