This forum is great! I found it very-very useful. Very-very thanks all! And finally, where to buy? Here is the examples which i know:
1. http://www.srsmicrosystems.co.uk
2. http://astore.amazon.com/digicamguides-20
3. http://www.parkcameras.com

Anyone knew any alternative?

PS - i whant to buy Pentax k20d kit

I found one site www.justcam4you.com. What do you think about? Why prices are so low? I whant to purchase Pentax K20D Black + 18-55mm Lens Kit. Sale Price is €470.00 and shipment to Stuttgart is free! Is this possible? Someone bought something there? To buy it? Or any alternatives?

Sorry, my english is very bad!
