you can always look for a 2500 (Barton core) Athlon XP and overclock it to a 200 FSB, it will run identical to a Athlon XP 3200 2.2ghz ..
the 2500 (barton) cores are great overclockers.. the run stock at 166FSB but you can easily run the FSB at 200 and achieve 2.2 ghz without any modifications..
I am currently running a 2500 at 200FSB 2.2 ghz .. no problems... it also reads as a Athlon XP 3200
