Eibacks installed and looking an alternative to Tokicos and KYB's

I just installed the Eibacks on my ride. Lowered it nicely and did the antipogo trick as depicted on http://www.clubgp.com(Thanks ripn12s) but did not installed new shocks. The ride is pretty nice but would like to get stiffer shocks. Are there alternatives to the Tokicos and KYB's? No Monrow please. ;)

Check out the Koni Sport adjustable struts. A little pricey, but hey......
