You'd probably be able to do it using the latest version of nero and a SATA BD-RE drive in your PC. They are now available from newegg.com for 600$ (said model is now $570 with MIR and comes with a 25GB BD-RE).
Still a bit too rich for my blood, I paid 80$ for the dvd burner I have now back in the summer of 04 and it was still a bit pricey then lol. Seeing as how I'll probably be a college kid (for either 2 or 4 years depending on if I go with civil engineering or computer science) I won't be dropping money on a blu-ray burner. I'll wait till I'm done with school that way I can build another nice new computer and pick out a sub $100 BD-RE drive from newegg =p
The PS3 wont burn anything at all, its a ROM drive only.
