The next step up is a coil-on-plug setup from Clewett, which also eliminates the distributor. Price in the $1700 range. You will need a PC or PC emulator to program it.
As Charles "Boss" Kettering used to say, "the part not added costs nothing, weighs nothing, and won't break."

Right, but you lose your tach signal. Requiring a simple circuit, e.g. a couple resistors & a diode, to develop a low level (~ 7V) signal from the coil.
