I know everyone has been recommending Elitefts -- and having ordered one myself, I think they are the best racks available. However, not everyone needs one. I'll break down the advantages/disadvantages:
ELITEFTS.com rack advantages
-- holes up top and bottom for attaching bands (if you don't know what these are for, then you probably don't need it)
-- narrow spacing for doing exact pin presses to work specific bench sticking points
-- high quality construction (these racks are meant for powerlifters, so they will last forever and can handle as much weight as you can lift)
-- disadvantage: high cost
-- disadvantage: shipping (costly and they use a third party, so basically a truck will just come by and drop off the rack -- it's up to you to assemble it and carry it inside the house)
STANDARD POWER RACK (most of the racks you listed seemed to be pretty "standard")
-- suitable for most people, durable enough for the average lifter
-- you can save on shipping by buying local
-- many newer ones have the optional cable attachment, which is convenient
-- disadvantage: durability will be an issue if rack is used frequently and with heavy weights
My suggestion: if you don't need the features of the EliteFTS rack, just get one locally. I've seen similar racks to the ones you listed in my local sporting goods / fitness equipment stores. You will save on shipping that way. Just look for good quality construction (as little plastic as possible).
Also, the thin spot bars are better than the thick lever-activated ones. A lot of newer racks have the lever spot bars because they are easy to adjust, but stick with the solid bars that you have to pull all the way in and out (they will last longer and it's safer for heavier weights).
