unless this is a person to person deal, then i wouldn't do it. might be a scam if its online. he can sell that equipment for so much more. well i dunno.
Be careful a couple of months ago someone on eBay was selling a 13w7 in a H.O box brand new. Buy now was set to 450 bucks. It took me well over 2 hours to consider buying it. By the time I was going to buy someone had beat me. A week later I check and that person never received the sub got rip off.
im sorry to send you so many emails, but i am just very curious why your price is 500 dollars shipped. on ebay each of these things can easily sell for 600 bucks, you are you selling about 2400 dollars worth of stuff...for a mere 500 dollars???
seems to good to be true..
thats what i sent him....ill update you with his response
