Anyone tried one of these HEI Distributors?

As i have said in another thread, this is the cheapy Chinese dizzy my friends and I use.
Before we even install them we replace the built in ignition module as they sometime fail or not even work at all.... Done!

Its not really a HEI dizzy though, it it just a basic electronic dizzy with the module built in.
To make it HEI you need a HEI coil and bigger plug gaps.
