This is what damages DL...people thinking that these are gotchas. To be fair, it's in T & C and it's widely known you'll need to buy an expensive M fare and gamble on Z opening up. It's less of a gotcha than the notorious award booking tool on DL.COM that presents you with SM demands that make no sense even according to the rapacious three-tier redemption structure.
Were you aware that the SM director himself, Jeff R, publicly called his own PMU product "broken"? That ought to give you a clear enough signal about the worth of the PMUs.
I chose the 20k SM, about which everyone knows how I feel. But they're still worth more to me than the PMUs.
