Whether it is a PowerPro or dvrplus+, keep in mind we are primarily buying a motor. Yes, I know there is the new 2 bearing quill, which you may or may not need (or want). However, you are primarily getting a motor. If this was a 10ER that needed a new motor, what choice would you make? Would you buy a $1000 Shopsmith 10ER motor, if it existed or a $500 Baldor motor or a DC variable speed motor from MKC tools? If you have a standalone drill press, bandsaw, etc., etc. in the shop and it needed a new motor would you use the original brand motor that went into it, or maybe upgrade to a Baldor or any other motor that you choose? Granted replacing the motor inside the Mark V headstock is a bit more challenging than these other applications so you could say that the PowerPro or dvrplus+ is a service, so you are paying for the $500 Striatech guts + 2 bearing quill + man hours of doing the upgrade work. Sure, part of that cost also goes to overhead for the warranty. I like to reduce problems down to their simplest form and for me, the PowerPro is now a $2.2k motor upgrade. You know for that kind of money, I could get a new "motor" for my car...that is some serious coin. Also, does anyone actually use their PowerPro, on a regular basis, to do shaping at 10k RPM? To me that 10k RPM upper limit is like the big number GHz sticker on an electronics box.
If a Shopsmith owner is comfortable with the risk of buying a dvrplus+, then that is $1k still in their pocket for other tool purchases. That risk entails that if the person offering dvrplus+ stops doing so, then either a) they might have to fix their own headstock, or b) find another person that works on headstocks willing to attempt it, or c) buy a new/used headstock and start over. At the end of the day, I am not trying to talk anyone into or out of buying a PowerPro or dvrplus+. I am just hoping to bring some perspective to this discussion. Until recently, Shopsmith was the only game in town when it came to PowerPro. Noone knows where this dvrplus+ effort will go, but as a Shopsmith owner I am grateful that there are choices now.
FYI...For comparison a Powermatic PM1000 (1 3/4 HP) TS motor replacement is $433.49 from the manufacturer, but of course this is a bolt-on replacement.
