Chassis braces HELP what are the best?

I've recently got a 2001 toyota celica 140 in brilliant condition and i want to start modifying her. I'm planning on starting with some minor handling changes. I want to know which chassis braces are going to be most effective, what style should i look for and are certain brands better then others? Also what sort of price range would I be looking at?

All brands will boast they are the best but pretty much do the same thing.. Don't buy cheapest as usually no good tho.. Buy a named brand and should be started
