Welcome to CDFreaks!
Top 5 ... I would think most would include TY and Verbatim in that list ... most likely at the top.
Online ... some good suggestions made already. Judging from most people's experiences, you can't really go wrong with Rima.com.
Local (Colorado) ... you should check out ripit's weekly post in the Bargain Basement thread.
From the litter of local 'box' stores, these are most likely your options for TY media under these brands:
Fujifilm 8x +R: YUDEN000 T02 ( MADE IN JAPAN )
Fujifilm 8x -R: TYG02 ( MADE IN JAPAN )
SONY 1-8x +R: YUDEN000 T02 ( MADE IN JAPAN )
TDK 8x +R: YUDEN000 T02 ( MADE IN JAPAN )
TDK 8x -R: TYG02 ( MADE IN JAPAN )
NOTE: Fuji's are phasing out their TY media and moving towards media from Taiwan, so be aware of that when you look at the product packaging. In most cases (of the 3 brands listed above), the Made in JAPAN media will be TY ... with the EXCEPTION of SONY 1-8x -R's (which are SONY's own media MID - ie. SONY 0D11 or something of that nature - THIS IS NOT TY).
Each brand also has Taiwan made media as well ... so, do yourself a favor, and inspect the packaging very closely to make sure you get the Made in Japan media (again note my comments on the Sony -R's, which are not TY even though they may be made in Japan).
TY ... YUDEN000 T02 & TYG02 both are excellent media. Your particular burner (you should mention what you're using to get a better response) may prefer one and/or the other. In most cases, both work just fine.
This week ... Fuji's are on sale at Best Buy and Staples. Good luck.
