Aftermarket front sway bar choices

Can anyone tell me what's the best choice for an aftermarket sway bar? I've read about them but there's conflicting results.
I need a 'kit' as the car never had one... and stock stuff isn't available around here.
Is it Hellwig or Hotchkis and that's it? Pricey stuff (I'm in Canada).
It's a stock front end with a disc conversion.
