You may want to try Micro Center. I've seen 20 packs for around $25 - 27 and they were Verbatim made in Singapore discs. These are considered the best.
The bitrate won't much matter at either 7000 or 8200kbps if the source is no good.
If you don't want to spend extra for DL discs, give
DVD-Rebuilder a try. There is a free version available and it gives great results with "HC Encoder" built-in. For just over an hour shows, you probably won't see much difference if any at all. I make my deciding factor on whether to use a dual layer disc based on how important the video is to me.
