Nokia 770 - keyboard question

[Vaughn Treude]

Hello all,
This isn't an off-topic question, since the Nokia runs Linux!
I have a Nokia 770 and like it very much.  I need to get a Bluetooth 
keyboard.  I hope there are some Nokia users out there that might have 
an opinion on which to get.

1. The Thinkoutside Stowaway _Universal_ Bluetooth keyboard gets rave 
reviews, is definitely compatible with the Nokia, and retails for $150. 
  (Ouch!) It's a small, four-row dual fold keyboard.
2. Stowaway also has another Bluetooth keyboard that is not designated 
as "Universal."  Don't know if it works with the Nokia; and I'm having 
trouble finding that info due to Thinkoutside's confusing and 
inconsistent use of product names and numbers.  It's $120, and not as 
compact as the "Universal" model.  The keyboard has 5 rows, and is 
touted as "full size."  I would prefer a more familiar layout over the 
smaller size, as long as it works with the Nokia.
3. Freedom's Universal model is cheaper still (retail price $90).  It's 
got five rows, and I understand it works with the Nokia.  But how is its 
quality?

I'd appreciate any feed back.
