It seems the only suspicious reason why it is fishying ad is that he requires bank-to-bank wire transfer.
But actually I've seen the same picture in my local craigslists that is selling the same Meade 14" SCT. He was asking $1000 and I followed up with him to see he is scammer and ended up with escrow service that I've never heard of it and I couldn't find any record of it in Google and requires fund with B-to-B wire transfer through Western Union.
I can see the same writing habit in his ad too.
I'm quite sure he is scammer and I recommend to stay away from that ad.
But if you want that item badly, please be cautious.
