"I joined the list just recently and feel pretty lost because of all the
abbreviations. But, could you just give an approximate cost of one system
the other. (Spark gap vs.

	Ouch, that's a difficult question...

	Ok My last SSTC cost me around $100, but I had a lot of the sundries
	My last SGTC cost me around $70, but I didn't pay a thing for the
neon sign transformers.

	Basically you can spend as much or as little as you like on any
coil. It is possible to construct a Spark Gap TC totally from junk yard
stuff. With the semiconductor coils, this is much harder to do, as you will
need the silicon (transistors) that are going to stand the abuse, and they
don't come cheap.

	If you are just starting, start with a classic TC, a fan blown
static spark gap, a neon sigh transformer or oil burner transformer. Then
get the feel for making TC's before going to the electronic coils, this way
you will save $'s in blown chips and Transistors.
	The Classic TC's are much more robust and forgiving...
