Koni yellows and Ground Controls are the best thing for the money if you want adjustability and longevity. Koni DOES build threaded body struts, but those get to be really expensive and you would need to know how you want them valved.

I have a friend who bought Konis to replace his AGXs. Jeff has a 91 ZC swapped sedan, btw, that is driven in autocrosses and at NASA track events. He says the difference between the Konis and KYBs is very noticable.

Tokico blues aren't too bad, but they are valved very similar to the stock Honda struts. We have blues and a no name coil over set up on the club's '88 CRX and they have held up ok. The car has only been driven at autocrosses for the past several years, however.
