[link|http://www.newegg.com|http://www.newegg.com] lists an [link|http://www.newegg.com/app/viewProductdesc.asp?description=19-103-506&depa=0|AthlonXP 2500+ (Barton)] except it has a 333 MHz front-side bus. Getting DDR400 memory isn't necessary for such a processor (unless you want to overlock it or have an upgrade path in the next few months). If you can get a faster processor for a few dollars more, try to do so. It might be tough as the AthlonXP is being replaced on the low end by the Sempron and on the high end by the Athlon 64.

How much system memory are you getting? You have 2x512 and 512 listed. I'd go with at least 1 GB so you don't have to think about adding more for a while.

I can't comment on whether the price is good for your area. It's a shame that they're higher than in the US, but having a real person you can go to in case of problems is an advantage. See if another local store you trust will give you a quote. That'll give you some idea of how the prices compare.

HTH. Good luck!

Cheers,
Scott.
