Sensor Cleaning

I have a bit of dust on my sensor of my K-x( I think ) and need to get my first sensor cleaning kit. However I am not sure which is the best option. Seems to be a lot of different opinions out there.

Do I go for the arctic butterfly - which some seem to swear by;

Do I go for this Jessops kit;

Do I simply get some swabs like these;

Or something else?!

1 vote for the Butterfly. It has served me well.

Second vote for the Butterfly. Dead easy to use and very effective

Do you need to have some sort of viewing scope like the one that comes with the jessops kit as well? or do you make do without?

I do without. When you use the Butterfly you clean the whole sensor, you'r not trying to pick off spots from here and there.

I use swabs and fluid. Works a treat.

I have just started using the butterfly after struggling with the Pentax swab kit. Its the butterfly for me now, so easy and effective.

Both have their merits - butterfly is great so long as the dust has not welded itself in place - if it has - then swabs are the answer IMHO

Thanks for all your help so far.
