[nolly]

I dropped to dough on an Artic butterfly kit from Visible Dust. It works great. I've only needed to clean the sensor once with it, but its fast and pretty easy.

A reusable kit will pay for its self overtime compared to paying a camera store to do it for you.

When changing lenses, try to keep the camera body pointed down to avoid dust falling into the opening. Avoid dusty areas if possible when changing lenses. Keep both ends of you lenses clean (keeping the mounting end clean will help prevent dust transferring from the lens to the body). I change lenses frequently, and don't have many problems with just following those 3 "rules".

Hope that helps
