Given your proximity to Portugal...have a look at the Semogue brushes at <!-- w --><a class="postlink" href="http://www.vintagescents.com" onclick="window.open(this.href);return false;">www.vintagescents.com</a><!-- w -->
If size really does matter, check out some Chubbies.

Don't know anything about Semogue but I like the Simpson Best hair.
The Simpson Commodore X3 would be a nice upgrade to a larger and softer knotted brush suited to face lathering with a substantial handle at reasonable cost.

For great value I wouldn't hesitate at Penworks, he's got a sale on....the 24mm Finest knot for $40.00 in horn or the larger 26mm brushes near the bottom of the page for $48.00
