I hadn't noticed that.  I have the one Jayson is selling.  I'll have to see if there's anything printed on the one I just bought a month or two ago that suggests one or the other.  I've seen them come down to $120USD or thereabouts so I thought that's why Jayson had dropped the price, he was just staying competitive.  I can tell you that full out, my Gen-X completely overwhelms the overflow on my 72g.  Even T'd off to run a RSB, the remaining flow needs to be cranked back to about 40% open.  There is still some serious flow coming out of the sump return.  Like you once said (or something like it), I don't want to sound like a cheesy endorsement, but this pump has been the best $200 I ever spent on this hobby.
