I have $2000 to spend on an MBP. I'm in college (so I have the education discount), which only allows me to go for the low-end model new, with a little cash left to upgrade the RAM. In the refurb store, I could get an MBP at 2.6 GHz, 160 gb hd, and 2 gb RAM, 256 mb vram. It looks like an incredible deal, and I'd love to have a 2.6 GHz processor, but it is the last generation. Is it a better deal? Will the faster processor compensate for the older architechture?
