Lenovo ThinkPad R61 T7300 + 1Gb Ram + 80Gb Ext HDD @ Harris Tech $1799
The base price for the laptop @ $1799 is already cheaper than I can find it elsewhere - although I'm sure there will be someone - by about $100. What makes it a good buy though is that the nearest other machines dont have an extra 1Gb of RAM and dont have the offer of an external 80Gb hard drive.
So all in all - a good buy I reckon. The only thing with this machine is that it comes with XP Pro. The $73 you get in cashback will more than cover the delivery.
