I just ordered and received a portable Altec Lansing speaker from Amazon. It is the Orbit iM207. Amazon has it for $14 plus change, but there is a newer (more expensive!) version just out that addresses a few customer complaints. It has great sound and is very kight weight. It is battery operated and can use rechargable batteries, so you won't drain your Fuze.
It is worth looking at - both the new and the older version!
