Memorex DVD+R media

I have a Hewlett-Packard 8x Internal Double-Layer DVD±RW/CD-RW Drive Model: dvd630i. I have been using Memorex DVD+R media with absolute perfect success. I have made over 20 copies and I have not had one bad burn so far. I would like to know if there is any other media that would be comparable to the Memorex DVD+Rs, but a little less than the cost of the Memorex. I know I can’t be positive that any media will be flawless, but I was just hoping someone else has had some experience with this drive and media. Thanks
