Sampletank marketing is tricky. They often run super hot, great, once in a lifetime, flash sales. After all the discounts, I bought my Sampletank 3 full for around $30 about a year ago. Program is ok, if you are looking for extra sounds and you get it cheap.

To me, the downside is that S.tank dropped GM support after version 2...Overall I think Halion by Steinberg is a far better choice than ST. Just an opinion.
