It's definitely worth it and only about $5 a month.
Try a place like this:

The advantages are you can set up your own web site so you look more professional and you can provide direct links to your MP3's etc...
Like instead of doing links through soundclick or whatever where they post lo-fi recordings, you can upload a hi-fi recording to your own server and provide a direct link like this:
http://s93744050.onlinehome.us/MoogBoog_Schmange_320.mp3
.... or do press kits like this:

(heh...like the way I subtely wove in links to my own websites?....mwahaha...)
