I'll start out by saying a thing or two you already know.

Starting problems can be traced back to faulty electrical systems/connections, fuel, ignition; compression.

If diagnosis indicates the problem to be plug wires, you do not need to change the entire wire, but merely the resistor tip end - 3 to 4 inch long metal piece. These literally screw on and off the wire, at least they do on my vehicle.

You can buy them in a number of places, including this site. Changing the entire wire involves pulling the other side off the dist. cap. It's not really hard, but rerouting the 6 wires thru the plug wire strips that snap on to the cyl. head is a pain. The wire itself is metal vs. the junk used in Asian/Domestic cars. It's not likely to wear.
