We shopped jibs for our Canon 5DmkII package for awhile and we recently purchased the EZ Jib from ezfx.com. We bought it with the extension kit, which I highly recommend. It provides plenty of height, the build quality is good and it's a piece of cake to assemble. We also got great service when we called with questions before purchase. We'll be adding the wheels to it soon to make it easier to move after it's set up.
