The Lens Baby lenses are cheap enough to buy and try and then sell if you don't like it. I sold mine for exactly what I paid for it. I had one for a while and never really warmed to the effect. That's just me, though. The lens is easy enough to use, although on the T-series Rebels the manual focus can be tricky.
