Your list does not include any of the Canon EF, or EF-S lenses. The Canon EF 100mm 2.8, or the "L" version of the same lens, can be had for reasonable amounts on the used market, and are great lenses. The EF-S 60mm is made for the cropped sensor, as in your camera. Even the old 50mm f1.8 can be used for macro, using extension tubes, with good results. Try KEH.com, they have many of your macro used lenses.
I have also made use of the Minolta 50mm totally Manual lens. I have a Minolta adapter and extension tubes for that -- AS Well as a Bellows. With that "Minolta Method" I use either the 7D and or the 5D Mk II -- AND using the "Live View" I can focus very well with the X10 enlargement on the LCD.... (As You All May Know = The mirror is Up and does not drop, so no camera movement from the dropping of the mirror back to position.)
As a side note to my earlier post here the Canon 100mm / 2.8 Macro IS the Canon EF.
