Recommendation….

That’s not easy but I’d go for one of the more business-like themes, i.e. iNove.
Although I can’t recommend a particular theme: have you had a look at this or that?

If you are using WP 2.8, go to add a new theme, leave the search field blank, and press search. That will bring back 34 or so pages of themes you can browse to see if there is something you like.

Cheers guys
