Best External DVD DL Burner for buring game iso's?

So i have a DL burner in my pc but i don’t think i can get it to work properly so im looking to buy a USB DVD DL burner but don’t know which one is the best for burning xbox360 isos.

Do any of you guys have suggestions?

Where are you located? What models or brands are available at your local stores? External drives are more difficult to recommend, because they aren’t as widely and universally available as regular internal burners. You can find some models one place, other models elsewhere, and even if buying online, they can be expensive.

I live in the US, and i’m going to buy it online
