Help with an IDE Burner

Hi guys,
I have a TDK880N (I guess back in the day I bought it new I flashed it with TDK882N or NEC-2510 firmware) that currently stays in my Powermac G4:

Powermac G4 Gigabit Ethernet
Sonnet G4 1.2GHz CPU
2Gb Ram
Sonnet Sata PCI Card
500Gb Samsung F3 HDD
MacOS 10.4.11 and 10.5.8

One of this days I bought blank cds from Verbatim to burn Lubuntu for powerpc, the drive couldn’t burn the cds (Gave an error).
Burned the cd in another pc (with an asus sata burner) and tried the Powermac to read it,nothing, it detects the cd as blank.
Tried the sata burner on the powermac:
OSX 10.4.11 doesn’t detect it
OSX 10.5.8 detects and can read the CD fine.

So guess my TDK880N is passing away right?

1)Is anything I should try before buying a new one?Cleaning Lens “cd” or updating firmware?

2)Since 10.4.11 can’t take SATA Burners, what would be a good IDE drive to choose?
I’ve seen used ones:

Plextor PX-740 -15eur, from what I’ve searched it is a Benq 1640

NEC ND-3520A - 15eur

LiteOn DVD8900 - 19eur.guess it is a Benq DW1670

I wouldn’t like to past the 20-25eur barrier.
Thanks a lot
