It probably comes down to a higher profit margin. If they can dedicate more
mfg space to equipment to make the more profitable lathe, they can be yet
more profitable. Plus with more volume they may lower their motor costs
significantly. Maybe they want to raise the standard for an introductory
lathe. An introductory motorcycle or snowmobile can be $3000-6000 for an
adult so why does a lathe need to be $900? I suspect the sales volume for
the DVR is not 10% of sales for the Nova but rather 70% or better.

One smart thing about the Nova line is their light weight/price. So
shipping can be included in selling price without the seller losing such a
high percentage to shipping. The Nova DVR makes this ratio even better.
