Pioneer DVR-A06/106 or A07/107. I did some shopping around before the holidays and the Pioneer models are well regarded for compatibility with media and tabletop DVD players. They're a few bucks more but worth it. The 107 are 8x (both -R and +R, I think).
I have a Lite-On 411s which is a 4x burner, and its been great. Its also a dual format and I havent had any problems with it. Here is a review of it: http://www.cdfreaks.com/article/127
you can always find them rebadged and after rebate for about 80-90$ might wanna think about that . Office max is great for that . but the trick is when they are on sale go in a few days AFTER the sale starts . hopfully the item onsale is sold out and ask for the sub . i did that a few weeks ago and got a pacific digital ( rebadged liton LDW 811s) for 79.99 out the door . they sell the subs at the after rebate price . it is a great way to werk the system .
