A variable rack is much more difficult to manufacture and to package, so to say it costs the same is ridiculous. If it did it would be standard fitment across the range. Tip: never ask a salesman for highly technical information, some are technically minded most aren't.

2) of the many complaints on this forum about "steering wheel vibration", only one of those complaints comes from someone with VSS?

I suspect there are more differences, software and/or hardware, between the two.

My .02,
Because they aren't 'just a little machining different'. The two racks are significantly different. Maestro is correct in saying the ratio's are not that different up until 90-100 degrees of lock, but the mechanism is different, so the overall feel is different too.
