Richard, I suppose what Evo and I were both saying is that your enthusiasm for the AthlonXP may be well founded technically, but for Helen's purposes a 900 Celeron would fulfill the same functions perfectly well. It's sometimes difficult for someone who KNOWS all the advantages of various things to accept that a lot less is still acceptable.
Helen, if you take Richard's suggested make, you can't go wrong as long as their support is reasonable.
