Used 912s can be had for $7k-10k. Not dissimilar to a used O-200. And only $1k-3k less than a VW engine.
A new O-200D is $23,500 and a new 912ULS is $18,500. A new Revmaster is about $8k.
Personally, I think a VW engine is the wrong choice for a 701. A 2180cc VW makes about 76hp and weighs 161lb...the power to weight just isn't there. It will fly, but it will turn a STOL airplane into a sorta-kinda-STOL airplane. Just IMO, of course, but we have a VW-powered 701 locally and it's kind of a performance dog.
