Yeah there are quite a few places (including some online you can ship to - check ebay) that will repair it.. if it's not a BC unit, you might want to consider just upgrading to a newer slim model.
I also have the original 60GB (upgraded to 500gb) launch model (never been repaired) still going strong but reading stuff like this I know mine could go at any time too. I'm almost tempted to buy another 60GB'er and transfer everything over just in case something happens to this one.
Keep in mind that if/when it DOES die, if you haven't backed up to an external HDD, you CANNOT just swap your drive into a new PS3 as the content is encrypted with a unique hardware key.
