i give up. i tryed to ignore the random spots that have been showing up on my pictures, but it's getting annoying. i never take my lens off, because i only have one, but the dust still makes it's way in there.

anyways, has anyone used one of those sensor cleaning pens? i see them for $20 (the ones with a little brush on one end and some cleaning liquid and pads). i'm kinda nervous about touching anything on the sensor though.

how delicate are sensors? if i buy one of these sensor pens and gently brush the sensor, what are the chances of me damaging it?

and if you don't recommend these cleaning pens, what other options are there? i don't want to send the camera away just to get cleaned. and there aren't any big camera stores where i live.

any help would be much appreciated.
