Did I get ripped off? Also, bad lasers, wrong media and strange modchips!

Durr. I keep having stupid questions;
The store that NoNo9 reccomended, that I was planning to buy the discs from doesn't know if these are G04 Riteks. They say that it doesn't say anywhere on the box or the DVD if these are G04 or not. The price is also a bit cheaper then in most stores, but not by much(15-20%). Should I watch out of them or are Riteks generally good. Are RitekWHATEVER DVDs better then the Memorex ones that I have?

Once again, thanks to everyone for the help!

Edit: Here is the link to the page with the discs. It's in hebrew, so it won't tell you much, but it has a picture there. Hopefully that'll help.

I purchased those disks from them a few days ago and they are indeed G04s.
