SilverSurfer: Should i buy it?

[AmigaMance]

Hi.
 First of all, i use the serial port of my A1200 only for internet access. I have a 56k modem, i usually connect at 44kbps max and i'm not planning to upgrade my connection.
 Silversurfer is not expensive, i have found it in most of the Amiga shops for 30 euros.
 So, my question is: Will i get any increase in my downloading speed? Even a small one?  It will be mainly for text files or for compressed binaries as well? (like JPGs for example, so graphic-rich websites will load a bit faster) I don't mind about text much, because it is fairly fast already.

 Thanks for the feedback guys.
 I see. It frees your CPU from the serial I/O process but it gives you almost no downloading speed increase.
The option of adding a PC mouse to the silversurfer sounds tempting though, because my Amiga mouse is going to die soon and it's almost impossible to find one in my area. But i think it would be better to buy a PC mouse adaptor like cocolino. (?)
