Sorry, but I can't help you with finding a 7228, at least not at any reputable establishment. I am currently running an Arkua 7528, which you probably saw over at NewEgg. The only difference is in the fan speed (5400 vs. 6800). It still gave me a significant drop in load temps over the retail HSF, without all of the noise associated with other higher RPM units. Just another option to consider.
