What about Spooky Central (Plasma)?
Spooky Central has just been released. It looks like a very capable system, with plasma, pulsed electromagnetic fields and ultrasound integrated in one package.
The price is very favorable - $1698 + $117 for the generator = $1815 for everything, ready to go. (Import duties excluded) You cannot find a similar off the shelf system for anything less than $8000, most likely significantly more expensive than that.
In my opinion, it is not worth it spending time & effort building your own rig, when a ready and asembled system is available for a few extra dollars, barely more than what you would have spent on parts for the do-it-yourself system.
However, I haven’t tested Spooky Central myself, so this is just my unqualified opinion.
