Curious about the cheap ebay alternatives for macro. I know obviously the best solution is a dedicated macro lens, but can't even think about it for at least 1-2 years. I just bought a canon 600d and am not allowed to open it for a week. So i did a little homework on this & would appreciate any clarifications.

1. 58mm Close Up Lens +1+2+4 Macro for Canon Rebel XTi XSi c.$17
These screw in lenses seem a really elegant & portable cheaper alternative, allowing use of all the auto features on the camera. But at this price, i wonder about the quality of the glass...

2. Macro Extension Tube Ring Loop For Canon EOS DSLR - about $12.
1x Camera body nount adapter 1x Lens mount adapter 1x 9mm tube (Tube 1) 1x 16mm tube (Tube 2) 1x 30mm tube (Tube 3)
I think you lose the autofocus with this? & they let less light in...

Does anyone have experience with either of these and have advice on the preference? Are these cheap ebay versions a bit of a trap?
