Linksys 802.11g Wireless Router with or w/o SpeedBooster?

Hi, I'm moving into my college dorm in a few days and my roomate and I were discussing wireless routers for use with our laptops. I know Linksys is a good brand and my local Best Buy has a sale on these two models:

http://www.bestbuy.com/site/olspage.jsp?skuId=6304082&st=linksys&type=product&id=1074787298555


The only difference between the two models is the bottom one has the SpeedBooster for $20 extra. Does anyone know if it's worth it? Is this SpeedBooster legit, does it actually work and will it come in handy in a college dorm?

Any help is appreciated.

 

Speedbooster only works with Speedbooster enabled cards. If you dont have one, then its not worth it.

 

Thanks for the help
