Altec Lansing iM413 sound system for Fuze... is wire antenna better than telescoping?

Hi. I hope someone can help me.

Alec Lansing has changed the antenna on the iM413 portable sound system for the Sansa…it no longer has a telescoping antenna. It now has a thin wire antenna (55" if reports are correct). 

I would like to get a good portable sound system for my Fuze and am limited to ordering from Amazon.com (gift card).

Should I try to get the earlier version of the im413 or is the wire antenna an improvement? 

Thank you kindly!
