In Australia, these are sold under the name "Crossfire" and are a few cents short of $50au.
My friend sells them in his music store, they are fairly well made. But as I don't have a DM-2 (yet) to compare it with, I can't make any comments about it sounding like one.
THanks Dr. Bob! They are $40 here plus postage. I'm very close to thinking it's worth trying one. Haven't seen a DM-2 go past for less than $250 in weeks...
