Which Menu Bar is SE friendly??

[lunatunes]

I have a question about adding a Menu bar. The menu bar I have on my site is not a BV menu bar.
Its just text links on a background shape.
Would I still be better off using a CSS text menu bar for SE purposes.
Or will the search engines be ok with my menu bar as is.
Here is the link: www.industrialsuppliesandservices.com

Also I read that SE dont like the BV drop down menu.
Does that go for CSS drop down menus also.

Thanks,
Randy
