Been a customer of the Kamerastore for a few years now, and never been disappointed. They always deliver quickly, from couple of days until — at the most — a week, and once the package is with the courier it's often 24h from Tampere in Finland to Portugal. Packages are always packed securely, and there's often a little sweetie treat in each parcel (I don't eat sweets, so can't tell you what Finnish sweeties are like, but the thought is appreciated).
Kamerastore has an excellent selection of cameras and accessories, and scouring the website is always fun. You never know what you might come across. Cameras are always described accurately on the website, and the images you seen are the article that you'll receive. Most of the time I buy the bargain 'Not Passed' cameras, as I'm always happy to put a bit of work into restoring the camera and if I can't then working around its flaws to get images out of an old camera again.
All in all, Kamerastore is always my go to supplier for used, weird and wonderful gear.
