It doesn't look like a reserve auction, $2,995 is probably the minimum price that person wants to get for the unit. Don't assume the seller will back out of the deal. If he gets rid of the Ghost he doesn't need the Argosy or the monitor arm. So it makes sense to give one low price for all and try to move it.
Also, pickup only auction items tend to go for less because you have fewer people bidding on them.
I don't know that seller, but the deal looks pretty good. Since you'd be picking up, you'd ahve a chance to check it out in person as a last resort.
