The question is, is there support in the latest firmware for some 8X/16X media.
With the proper firmware support, Verbatim -R (8X: MCC02Rg20, 16X: MCC03Rg20) can burn very well at low speeds. I used some in a @1X standalone recorder and even though the scans were not for the hall-of-fame, the discs are perfectly usable.
Without the proper support, though, you'll probably get only coasters.
Considering the price of burners nowadays, indeed you'd be better off with a recent burner
