so the eBay auction price dropped even further, so it came down to a $115 difference (upgrades: HR Glossy --> HR Matte, i5-->i7, 256->512MB), so i bit the bullet and bought it. the only downside is it has the 5400rpm HDD< but i can upgrade that for ~$100.
i will have to deal with the inconvenience of returning the Macbook pro i ordered, but from my understanding, the restocking fee only applies if i open the box (and i haven't even received the shipment yet).
i'm actually going to start a new thread to ask a question about what i should do with my i5 (i'm considering reselling it).
