LG VX-5300 / UX-245 / AX-245

Can anyone help me? My husband and I recently got these 5300s, and while we like the phone, the ringtone options are terrible! This is one of the only phones that doesn't support the Verizon Tunes and Tones thing, so we can't get real tones that way. I was going to purchase a song through Sony Musicbox, until I discovered it will cost at least $4 for just 1 ringtone!

I tried accessing the mobile17 thing, where you can upload an mp3 for a ringtone ... but it doesn't support this phone, either.

Are there any phone-savy people out there who can help us get a REAL tone on our phones (not the cheesy polyphonic kind!) for less than $4 a pop?? I was recommended to this site/forum by a Verizon employee, which was cool - I hope it's helpful.

Thanks!
