Something smells here.....before you bid, I'd ask about the shipping. Sometimes a clue to scammers is the information they put in the shipping description. This ad lists USPS Parcel Post....USPS won't ship an item this large and heavy. Same with the "Worldwide" shipping option. Scammers like finding accounts with great feedback and then "take over" them. They also post previously auctioned merchandise using the pictures and description from another sale. They typically do this with high-end items to make it worth their while.
When I see an ad that doen't ring true, I always ask the seller some specific questions that only a person who actually knows the merchandise is capable of answering. If the response is vague and shows a lack of grasp in the English language, I don't bid. (Not that non-English speakers can't be legit....but in this case you have a well-written ad and frequently the scammers will respond with mis-spellings and poor grammar....giving you a clue that they aren't the same person who wrote the original ad.)
If it were me, I'd ask for specific shipping cost to my zip code, ask why they are selling it, how much they paid for it, how much it weighs and maybe a phone number that you can do a reverse-lookup on. All of these things can cause a scammer to not respond or give bogus answers that you might be able to detect.
If it checks out, this is a great toolbox and I would be surprised if it went cheap. Sorry if I sounds like a wet-blanket....but I've come across quite a few deals that weren't. Fortunately, I haven't gotten tricked....yet.
