The old stuff was teh shit - Old Orion and Viper amps are awesome as hell. The new stuff is decent for the money, as long as you're not going for a lesser line of theirs.
Isn't there a JBL 600.1 in the classified for $130? Infinitely better than that Directed IMO, used or not. I didn't know Directed had resorted to using max power ratings when naming their equipment. =\
