Woot has been selling some refurbished HP's for real cheap. I got a 15" for $179. Has something like 3meg mem, 60 gig hd, dvdrw/cdrw, 2.2mhz processor. It isn't by far the best you can buy, but if you are just doing spreadsheets and such, it is fantastic.
Bought mine 3 weeks ago, but have seen it for $199 three times since.
