while the power deal I have certainly earns some profit for me.
So today for me this is a power game not a gear game.
there is no bleeding edge gear for me to buy from someone I trust and believe in
So that all works for you (which is cool). But where I am, with my setup, there's no way on earth I can make any power deal that will pay off in less than 20 years (and chuck knows where I'll be in 20 years' time).
The only gear that *could* make sense to buy currently are FPGAs and - as you basically said - that's still a gamble.
I've changed my power company as the previous one was about to increase electricity costs by something like 40%. The new company now just announced they'd have to increase the kW.h rate as well...

So there's no escape. Only managing as well as I can.
