Keep E6600 or buy E21*0

[Jamous]

Hi people!
I've just upgraded from my E6600 to Q6600 and I'm wondering what to do with the E6600.
I am am planning on a mega-tight budget pc for basic net stuff and to use as a test machine for when I'm building pc's.
Should I keep and use my spare E6600? Or flog it, and buy a low-end C2D E21*0? I'm wanting to keep this as cheap as poss, so if I did sell the E6600 and bought an E21*0 the I should have a couple of quid in my pocket, or are these E6600's not worth much these days? Ta
