Also, can somebody please explain the pricing on these refurbished MBAs to me? its the CAD store here is the link:

Those with 64 or 80 GB drives are original v 1,1 MBAs. They have Merom CPU, Intel 3100 GMA graphics, PATA drive controller, 667 MHz RAM, and can drive a 23" ACD.
Those with 120 GB HDD or 128 GB SSD are v 2,1 MBAs. Those that have a 1.86 with 128 GB SSD are referred to here as rev B, but rev B and C are all the same v 2,1 MBAs. The June 2009 only brought a CPU swap upgrade with a tiny bit bigger battery and include a USB to Ethernet cable.
In that list. FROM YOUR LINK NOT THE PHOTO
1.8" GHz 64 GB Original MBA
1.86 GHz 120 GB rev B/C (Cannot tell but probably C)
2.13 GHz 128 GB SSD is a rev C
1.86 GHz 128 GB SSD is a rev b
Do not buy the first one.
The third one is the current rev c v 2,1 MBA. The last is the same price because it's the rev B upgraded with larger SSD. Apple changed the pricing in June 2009 so the refurbished rev B with SSD isn't any cheaper than the faster rev C with 2.13 GHz.

This one is your best bet if you can afford $1599. It's also only $50 CAD more than it costs in the US refurbished.
If you wait until Tuesday, Apple could drop the price on these SIGNIFICANTLY if it updates the MBAs.
