Outstanding offer?

I am very happy with my G3. I got it brand new at a bargain price.

Today I was offered a GF3 + 14mm for $210 USD. It was originally purchased last month and is used a couple of times. The seller has all papers so the waranty is good.

Am I wrong or is this a great deal? The 14mm alone is worth that price isn't it ?
How is GF3's IQ compared to G3?

Kind regards
