I am not very familiar with any of the MBP models. I wondering if this trade is fair for my iMac 20" aluminum 2.4 GHz Intel Core 2 Duo, 1 GB RAM, 320 GB Hard Drive, SuperDrive? Here is the MBP: MBP 15.4" 2.2 GHz Intel Core 2 Duo Proccessor. Running Leopard 10.5.2 (Includes new Leopard Install CD) 2 Gigabyte of Ram (upgradeable) 120 Gigabyte Hard Drive iSight Camera Built in NVIDIA GeForce 6800 128MB Backlit Illuminated Keyboard with ambient light sensor Slot-loading SuperDrive (DVD+RW/CD-RW) ExpressCard/34 slot, FireWire 400 port, two USB 2.0 ports, optical digital audio input/line in, optical digital audio output/headphone out He said he is willing to throw in cash too. My iMac is 3 months old with papers and his MBP is 6 months old with papers. What should i be looking for if i did this trade? This is through craigslist btw and I know i shouldnt be buying second hand computers, but it is still in apple warranty and extendable if it is only 6 months. Please help me make this trade smooth for the both us. I dont want to get ripped off.
