Here's so more info (was in a hurry)..
The Ivanko 6' EZbar being discussed is refered to as the OBZ-40.. It came new with a matching pair of COT1.25 compression collars, so make sure those are included.. They're awesome collars and Ivanko isn't producing them in the black oxide finish anymore, at least individually (wonder if they will still come with the new OBZ-40's???).
Here's an old thread that discusses the OBZ-40 and has some nice pics. This is actually the thread that I used to help identify mine before purchase.
As far as the 7'er goes, I admitedly don't know too much about them but I'd likely spend $150 on one.. As always try to get a few bucks off if you can.
