DVD Burner

I finally bought a DVD+-R/RW drive. It even does dual-layer burning.

CD-R$25100$0.25737280000$0.36
DVD-R$4050$0.804700000000$0.18

See! I'll save money inthe long run! 278 GiB or 64 DVD-Rs in the future.

Additional research shows that I paid too much for that DVD-R spindel at the store.

UPDATE 2005-07-03: Finding the cheapest source online, I get:
