Most Reliable Exterrnal DVD Burner

Hello and thank you for any help or insight you can give me. With so many drives currently on the market, I am utterly overwhelmed by number of reviews and stats on different burners. I am looking for the most reliable external dvd burner I get for less than $150. I will primarily be using the drive to burn movies on DVD+R media, and speed and noise are not critical criteria. I have had a few drives in the past and each one of them despite various operating systems, brands names, and software used, turned out a good share of coasters. For all I care, the drive could weigh 45lbs and be purple as long as it is super error free. With these aspect in mind, I would greatly appreciate your input/opinions.
