Depends I guess on whether you're willing to buy wheel spacers or not. If you do, you can get any Accord 4 bolt rims. If not, you're sorta limited here, unless you can find someone with contacts back in Japan. Watanabes, Longchamp XR4's, Hayashis, SSR reverse mesh, and Dori Dori rims are a few of the ones I used to see on street cars back there that could be put on a Z.

 

The reason for the Konig wheels being so expensive at MSA is
because there offering the wheel adapters in the package..But at that said their still $100.00 over the cost if you were to purchase the wheels and adapters seprately from someone else.
Your bolt pattern is 4x114.3 (4.5) If your going to use adapters then get an adapter at 1.5" thick and use a wheel with a +38 offset up to a +40 offset.for the rear ,you have more clearance so you can use up to a +42 offset.this is by far less costly if you were to get a 3-peice wheel custom made to fit without using adapters.You would be looking at $250.00 plus per wheel.
Just remeber to use a good billet aluminum adapter. I`m running 1.5" adapters and +40 offset wheels on my 1980 ZX
and they fit and look great, (4) brand new wheels on e-bay @ $250.00 and adapters $55.00 ea.total cost $470.00+good luck!!!
