Need DVD-ROM that reads both DVD+R and -R

anyone know of a good dvd-rom (reader) that reads both DVD+R and DVD-R discs?

i currently have an NEC DV-5800a and it only reads -R discs, but i have mostly +R media :frowning: any help is appreciated! thanks!

the Plextor and the new Asus (P1) drives read them for sure
theire both Pioneer drives btw, so i asume that pioneer reads +R as well.
