The 10-day Goenka retreat is most recommended. I did it several times, it's much easier than it seems and so so effective, and it is free of charge (you can give a donation at the end only if you did the whole 10 days).

Goenka's tapes are wonderful and amusing but hardly effective without actually doing the Vipassana course. It is the same case as with many of us that read a lot of spiritual stuff which is partially a candy for the mind but when it comes to meditation and practice they refrain. This is a barrier a true seeker should be aware of and pass. The mind wants the intellectual amusement but not to meditate because meditation weakens it and it fights for its survival...

They have centers in every corner of the world.

Goenka's Vipassana is not the only Vipassana and is not necessarily the Vipassana instructed by the Buddha as claimed.

It is yet another, though very popular nowadays, interpretation of the Buddhist Satipatthana Sutra, and an extremely narrow interpretation.

Goenka (following his master and the Burmese tradition) took the Vipassana to a too narrow interpretation of only observing body sensations.

The Satipatthana Sutra speaks about 4 types of objects to observe, only one of them is the body sensations. If you are vigilant, you will notice that Goenka disregards the other types of objects in an elegant way (maybe in order to keep the technique as simple as possible for the masses).

For beginners, this radical interpretation serves well as the mind is focused on one type of object and has no escape to invent bypasses and personal versions.

But for old students who practice Vipassana for a long time at some point the narrowed interpretation is not enough, they feel that something is missing, that the mind has found another back route of reacting. This is the time for such people to check on the other 3 objects: to ask who is that meditate, to observe the body as a whole, and to observe emotions as they apear directly as the sutra instructs to do.
