99 lowered Mustang GT-Need to replace struts/shocks

I need some help and understanding.

I bought it with Eibach springs, and I think Koni Yellow adjustable struts and shocks.

I need to replace them with something that is no quite as pricey as the Koni's, I think they are $600.00 plus.

Any ideas for a less costly replacement, a little tight on cash. How much roughly would the replacements be? What should labor run? Is there anything else that will be needed? I've heard Tokico's mentioned.

Thanks
