If you just want a little bit firmer and don't have any particular interest in getting way low, then eibach springs might be perfect. They are very affordable and offer a slight drop with a big performance gain. They are comfortable too, as long as you choose a good shock to pair it with. Lots of people use KYB AGX shocks with them.
I would like to add the KYB AGX sturts with the eibachs are great, I DD my Z & around town i can soften the struts up & if I feel like doing some spirited driving, I can stiffen them up. For your budget, thats the best option. I you have the oem spring & struts, they are probably already sagging & you are probably already lowered .8". I know mines was. If you go with anything else coils, or springs that go lowere than .8", you will have to correct the camber and toe. If thats not done your tires will be toast in a couple of months.
