Help for a CDRW first timer

[Mike da Gipsy]

Hey guys, first of all thnx to all of u who help thru this board
Now, about me dilemma
I'm looking for a CDR writer and I saw that Plextor and Yamaha r the best ones, now, what I need to know is how important is the EEF or whatever its called as the most expensive one is the only one who has it
I have my doubts between Plextor 24x(for $300), Plextor 12x(210$) and Yamaha 2100E (180$) All of 'em OEM (I live in Argentina so the prices may be way higher than yours)
My first demand its that it should run on a application overloaded PII400 Mhz W2k with 192MB RAM. That's why I didnt already go for the Yamaha, no Burn Pruf do nice 8mb buffer.
2nd demand. Be able to write as "deeper" as possible with CloneCD or programs like that so I wont have troubles copying a CD Audio or making PSX CD and PC games with no crack needed.

Any kinda help will be much appreciated
