I can also confirm That juan from cheap astrophotography is genuine and offers fantastic prices for used or even brand new DSLR cameras. I bought a brand new modded 1100d off him last year and it is amazing. You can also have it re-shimmed so that you can use a camera lens for daylight use aswell which was great for me in helping convince the mrs in getting a new one. He also gives you the orignal filter that he replaces with a badder filter. Service was great. always kept in contact. oh i did have to wait a extra week for my filter to come before he could start the work. So he through in a free 8gb memory card for my troubles. Would highly recommend.
