The 7106 might be found on the used market quite a bit cheaper than the 206. It is rated at almost, (aurally indistinguisable..) the same output. The 7106 is 160/100 at 4 and 8 ohms repectively, but can be bridged into three 320/8 ohm amps if desired. The 206 is 200/120 at 4/8 ohms. I don't know if it can be bridged as effortlessly.
