Gee, big surprise,...
The seller did not have the 520 power supply, nor did she know one even existed. Surprised? I'm not.
I did, however, make clear from the outset that I expect this M520 to be complete, board/mixer/cable, or it was a no-go.
The woman seemed slightly surprised and seems to want to cooperate, to backtrack to the church, and see if the PS-520 and CABLE can be located. Given that it pans out,... after all, this board came out of a CHURCH,... then, as complete, it seems that it will be a sweet deal, indeed.
If the P/S and cable cannot be located, resonably within a few days, then I told her to relist
the M520, less power supply, and that I would not buy it as incomplete, despite the bargain-basement bid.
See, if I pop $96 for an incomplete M520 now, then I'll spend the rest of the year, and easily est. another $300, just to locate and procure the power supply and cable.
That's no good deal, in my book. Well, maybe it is, but it's an open-ended gamble that I could find the power supply and cable separately, which is not a sure thing.
I bid on a presumably complete item, and if it's not listed as missing components specifically, then that's a flawed listing, for which I'm not obligated in the transaction.
Stay tuned.
