Just added another SP10 for my order...
Reason for my purchase is purely thinking about summer and heat issues... Frankly I believe SP10 will handle the hot weather better...
Bring the price down to $2,700 I will order 4 more instantly :-) and possibly more if I can sell my kidney.
How much you want for that kidney? You could sell both if you are willing to stay on the machine indefinitely. Would you consider a trade for a old Neptune order (group 2)?
