I had been wanting a Mesa Bass 400+, but in the interest of my finances, I've been considering some other options...like the Mesa D-180. Anyway, someone has asked me to make them an offer on theirs. He says that it has recently been retubed with Svetlanas, and is in good condition with some missing paint on the handles. He's also including a beat up (I think) Anvil 4 space rack case. What would a good price be? I haven't been able to find much in the way of going prices for these from internet searches. Also, I'm wondering if these amps are powerful enough for my needs? These amps are only going to pump out between 150-180 Watts. Is that enough to adequately power a 1000W 8 ohm Avatar 2X12 in a hard rock situation? I will also probably want to add another cab of some type come the fall. I don't want to regret the purchase later and wish I had just bought a Bass 400+. Any help or suggestions welcome.
