On no account rebid with this seller.
They are happy enough about selling it but only at the 'right price' and as you don't know what that is exactly, you could get let down again.
I suspect the computer they are selling is probably okay as they certainly seem to have confidence in it. They obviously think they underpriced it first time around.
But second hand computers are a risky proposition online. Quite a lot of them aren't what they are cracked up to be and on these forums, we see a steady number of posts from people complaining that this or that didn't work on their PC or laptop or parts were faulty etc.
You don't know that seller. You don't know if their valuations are realistic or not (some sellers, especially casual sellers, can have an over inflated view of the value of their personal items).
You'd be better off, on the whole, going to a retail store.
End of year sales are coming up. You may be able to pick up something at a good price if you shop around a bit.
The real bonus is, as sons& daughters says, you'll get a proper warranty. You won't on ebay, no matter what an ad says, unless you're buying from a retail seller anyway. So you may as well look for the sales and go in in person and have a look.
