$140,000 for a 2 acre sized liner, installed sounds pretty close. They also only last about 20 years on average for a good one. Bentonite, done right, will be pricey as well, but last for generations.
+1 on contacting Mike Otto...if nothing else, he may know some people to steer you toward from experience.
