What should I use for statistical analysis on Excel 2008 MAC?

I recently switched to Mac, and am happy with it. I just came to do some simple stats in Excel (simple, but beyond standard excel capability). I’d have used the analysis toolpak on my PC, but see that it doesn’t exist in Excel 2008 for Mac. What should I use instead? I found Statplus from analystsoft. Is that the best option?http://www.analystsoft.com/en/products/statplusmacle/
