Best Stepping

So my question is if I was to go out and buy a CPU today, what would the best one be? My current assumption is it would be the 1.4 GHz AYHJA Y stepping. Am I correct? Thanks for any input.

1.4 AYHJA are too expensive right now. I got me a 1.33/266 AYHJA "9" from newegg.com and paid less then 150 bucks for it. I have it at 1575mhz right now. Not too shabby. I hear there is a new AYHJAR out but I don't know the details on it only that it roxors. AXIA or AYHJA is what I say to look for.
