IME, $1500 (high mile stock)-$3000 (low mile or with extras), assuming you get everything
There have been some real steals that I have heard of, but in general the above seems to hold true.
Do remember that if you have to rebuild the engine, you can double those numbers or more. Considering that the '91 200q are 15 years old now, most engines that you find will likely need be gone through.

It all depends on how it was treated.
I have seen some with 150k that didn't use oil and had compression and leakdown specs acceptable for new engines. On the other hand, I saw one at 75k that had very loose valve guides and worn bores. If I had bought it, I would pull the head and inspect it.
Are you planning to run lots of boost? If so, I would rebuild the head and replace the bearings at the very least, and use the metal multi-ply head gaskets from the S4/S6. I would also seriously consider some performance rods. 3Bs have a nasty tendency to ventilate blocks with rods if pushed too hard (more than 22 PSIG IME).
Is it running now? Can you perform compression and leakdown tests? How does the inside of the valve cover look? My recommendation is that if you can't verify that it is good, assume that it is not and pay accordingly. Keep in mind that you can easily spend $2k rebuilding a tired engine.
YMMV

Rebuild
Mike,
I'm with Steve, any used engine you buy needs at least a top-end rebuild. Replace the exhaust valve guides, put on a metal head gasket and do the whole timing belt job. It's so much easier to do these things with the engine on a stand than in a car.
I bought a "well maintained" and "adult driven" 3B with 100K miles on it. In the rebuild I found a dinged piston, unhealthy bearings and all the exhaust valve guides were shot.
