Hi Paul...

if you have previous experience with coils  and a healthy bank account 
and you plan to persue this hobby for better than 2 yrs    then id go
for the 15KVA 19.9KV unit     if you want to keep the power down in the
beginning just ballast the input for 5 - 10 amps -at- 220V ( i use an EI
core with 200 or so wraps of #10 THHN solid copper wire) when you are
ready for more power add more EI cores in parallel ...
