Just to let you all know, my Mk 5 is dated from '85 and growing weaker. I did not do a scientific cost benefit analysis (my bride wasn't near), but in her absence, concluded that the Power-Pro was the way to go. Just to see the added improvement(s), sold me.

I like the way you think! (Thought) Similar to mine!

Just for kicks, thought to look up the price for a new complete Mark V Headstock. - - $1604.24 That's for a 120 volt unit, domestic. It's a bit more for 220 volt, or Canadian, or European units.

IMHO, the present day going prices for the PowerPro, are pretty good!

Something that came to mind because of the solid state controls and such on the Power Pro: Would it be recommended that a surge protecter be used so surges don't "smoke" something even when not running? Just asking.

That would depend upon how often your 'power company' creates/passes on to you those voltage spikes etc.

FWIW many are only good one time(sorta like a fuse) and do not provide protection afterward.

Not to concerned with the power company passing surges on but rather surges and spikes caused by lightning. I also consider surge protectors expendable like a fuse. A protector is a lot easier and cheaper to replace than a Power Pro.

Not being equipped with a lot of electrical know-how - gotta ask these questions:

Because the power supply is able to accept either 110 or 220, would this feature cut down on a threat from surges?

I am thinking the microprocessor items are located in the display/control unit. Maybe surges/spikes would affect only the power supply?

Trouble is, most are 'hidden' from view, or do not provide an indication of having blown.

Yep lightening a real worry(as well as charged clouds passing overhead).

Did I mention sun spots?:D

Electrical noise, spikes, lightening, = NO guarantees what will/can/may be affected. All we can do is 'try' to minimize the potential(pun intended)!

I don't know how much more susceptible the PowerPro electronics will be but it is certainly more susceptible than what we have been operating for these many years.

If I had one sitting in my shop (a PowerPro that is), I would certainly be unplugging it during the lightning storms that we have here in the desert.
