Canon Eos Rebel T3i Best Buy

Donald asks…Good or bad photography decision?I want to get some new camera equipment for some wide angle and macro. On amazon, I found a "Opteka HD² 0.35x Wide Angle Panoramic Macro Fisheye Lens for Canon EOS 60D, 50D, 40D, 30D, 20D, 7D, 6D, 5D, 1D, Rebel T4i, T3i, T3, T2i, T1i, XS, XSi, XTi DSLR Cameras" that i think I might want to buy. I have a Canon EOS 20D and I'm an intermediate photographer. Am I gonna get ripped off? Is this a good or bad idea?mr.eos answers:Well it's a converter
