I wouldn't!
You should see the acrimony over Moog making products for the 1%! Sweetwater is offering 24-month interest-free financing for a mere $1458/mo for the Model 55! That's more than my mortgage. Is it possible to rob one bank per month for 24 straight months and not get caught?
The 15/35/55 series re-issues are making use of the original diagrams and board films, NOS components that are long out of production, assembled/populated/tested and calibrated all by hand. The 960 sequencer itself takes 3 days to wire.
There will be 55 M-55's built, 35 M-35's, and possibly 150 M-15's in this current run, expected to take about 18 months to complete all of the instruments. If you bought it purely as an investment I reckon it will at least double in value within 10 years. With a rig like the 55 you are only limited by your imagination. Having two duophonic CV+Gate out (x2) keyboards is pure buttercream icing. The "sequencer complement" of two 960's and associated helper modules opens up so many possibilities it is mind-boggling.

DAYUM!!!
Seriously though, there is an upcoming firmware update for the Sub 37 that really makes the sequencer shine and mod destinations (there are something like 80 of them) can be selected by just turning the destination knob. Audio path is all analog. The sequencer can be played separately from the keyboard so it will play an outboard synth over MIDI allowing you to solo on the Sub. I'm looking to pull the trigger on a Sub37 in hopefully a few weeks after Sweetwater gets them in stock and fills back-orders. I need to send my Voyager to Asheville for the filter-glide mod and repair/re-calibration of the pressure controller circuit plus a couple other goodies they offer.
So much far out gear and too little time and money to buy and learn how to play them all!
