I am a newby and have a question for the experts. I have an opportunity to buy year and a half old equipment. It is as follows: (4) RF-7's (1) RC-7 and (1) RSW-15. Assuming there is nothing blown, what would be a reasonable price to pay for this equipment and is there anything I should look for while auditioning the speakers. I have to make a decision quickly. Thank-you in advance for quick, educated, responses. I posted in another category earlier so if anybody has seen it please don't flame me.
