I'd definitely bring a board along, and give it a test. But before that, I'd ask him if he's the original owner, about any proof of purchase, what projects he has used it on, why he's selling it, etc. If you make it to his place, look at his place if he has any other tools. No woodworker would own a DJ but no other serious tools such as a table saw or band saw, dust extractor and clamps for use with the DJ. He also should have some dominoes around, and not just the machine if he is the owner.

It being a stolen property would be my main concern, since you could try out the machine before you buy.

If the deal looks too good to be true, walk away.

It's a 200-240v tool, not likely to be in the US.

So does the 200-240v mean it wont work in the US or that it was stolen?

Ok, if I plug it into a 220v outlet in my garage, it should work fine right?  I was reading online that all Domino DF 700 XL's are 220 volt, so why would this one not be from the US?

DF700s sold in North America are rated 110V, not 220V. So are all DF500s. If the seller offers a 220V DF700, it didn't come from a Festool retailer based in the US or Canada, as far as I know. The last DF700 I used was 110V.

Right, my DF700 runs on 110 volts, not 220 volts.

At that price, I would suspect there is something wrong with it.

First off, the 220V you refer to may actually be 240V if you're in the US. It all depends upon what voltage your local power facility is sending your way. My local energy supplier consistently transmits 119V to 121V power levels on one leg which translates to 238V to 242V on combined legs.

The DF 700 you mention, will operate on 240V but this is not the norm in the US and this item is not a US sourced piece of equipment.  Normal equipment designed to operate on 240V in the US include ovens, clothes dryers, water heaters and central air conditioners. 

The thing you have going in your favor is that this DF 700 is rated for 220-240V at 50-60 cycles. That pretty much covers all the options despite it not being an official US released tool.   

Since it's a European model in the US, I would definitely want to test it first.  If nothing else, you need to figure out how the heck it plugs in!

If it's using some sort of Frankenstein'ed-together plug-it with a dryer cord and a plug-it, you would have to consider whether or not you have a dryer outlet available to use it.  If it's just using a normal EU-US adapter, maybe it's not a huge deal, but you still need to find a 240v outlet.  I have literally one in my entire house, and it's for my dryer.  The oven and range are both hard-wired, and I have no 240v anywhere else in the house or garage.

I don't know if it's a scam, per se, but something is definitely odd about this whole deal.
