Mike,

thanks alot for that css conditional statement idea. I used it and it works really great. I simply put embeded css style definitions in that conditional comments for IE greater and equal 6:
<!--[if gte IE 6]>
<style TYPE="text/css">
<!--
.odd #product
{
background-color: #c4b79d;
filter:alpha(opacity=20);
-moz-opacity: 0.2;
opacity: 0.2;
color: #beaa88;
vertical-align:middle;
text-decoration:none;
}
-->
<![endif]-->

Now the opacity is working only on IE6 and greater but my girlfriend (css is her hobby will try to make it work on Firefox/Opera too.
Anyway I also managed to fix this way the 2px difference mentioned by you before. Thanks!

Lyle you were asking about experiences with the Localization module. I would say it's a great fun implementing it - some things are easy - like translating contents - I had no problems with it, even though I don't have to translate every node because someone else will do it.
But there are some tricks that have to be done with cart buttons (next, submit order and so on...) I don't know if messing with code is necessary here but I decided to change cart.module a bit.
I have still a problem with catalog, cause there is a difference in spelling (english - catalog, polish/german - katalog). I only managed to change the block value, but after jumping on catalog page there is still Catalog all the time. (http://artofamber.com/en/catalog) After small "investigation" I figured that taxonomy module is responsible for that. Am I right? The problem is that my drupal/ubercart knowledge is really tiny and I don't know how to fix that. Maybe you could help?

Thanks for your support on that guys, I really appreciate that!
