the lens i use for all my macro shots is the sigma 150mm f2.8 which is a $1000+ lens. With the new canon 100mm f2.8 "L" lens out the older 100mm f2.8 non L is a steal for performance you can generally find them at roughly $400-500

I also have the 150mm 2.8 Sigma which I got for around $700 on sale. It does 1:1 at around 18".
