The majority of the site is free. I've got a fair few of my ringtones & SMS tones from there recently and haven't had to pay a penny for them. Admittedly there are some tones you've to pay for, but I think that they've been posted up there by unsigned bands that need the income.
This is all true...you can also use this site to make your own ring tones and wallpaper. you just have to have an mp3 file of whatever you want for your ring tone then the website makes a ring tone out of it. it just sends you the ring tone, wallpaper, or whatever viz text message
