info on memorex burner

[SamDman]

Hi, I'm anxious to purchase my first dvd burner. I really don't know what to look for in this type of drive. I have been waiting for prices to drop and I am ready now. I have seen a Memorex model:3202 3251 advertised for $250. Can anyone offer any info about this burner? I would also like any recommendations that you might have for my system.
p4 1.6ghz
80g HDD
512mb ddr
24x12x48 cdrw
dvd rom
gforce 2 w/ 64mb

p.s. would you get rid of dvd rom or cdrw?
