asterisk users - Jun 2005 - SPA841 Utterly Horrible, are there any good stun hardphones?

Hello All,
I have been using the following phones with excellent success inside my
lan:
Cisco 7960
Polycom IP600

I have also been comfortable with the SPA-3000.

I recently got a SPA-841 and the quality is aweful.  Even in stock
setup, it's like when I speak into the handset I sound like I am very
far away.

I want to get a hardphone for europe, but I need to be able to use a
STUN server, and have the ability to use multiple lines registered to
different providers.  The Cisco and Polycom do this well, but with no
STUN support.  Therefore I cannot just plug and play those units.

I also have a SPA2100, and it is decent, but not to the level of Cisco
and Polycom.

Does anyone know a good unit that could allow this?  Hardphone is
preferable, but I could use an ATA.  The cisco ata186 seems like it is
limited to one provider, and I want to set several.  For example, my NY
office, and a european voip provider.

Cost is not so much an issue, but reliability is.

Any suggestions?

Thanks,
Greg
