Upgrade for GSampler owners, till when?

[RaGe]

I was wondering how long lasts the $150 offer for upgrading to GSt ... I remember reading July 1st somewhere but since GSt seems so unstable I cannot afford to take the chance now.
Keep groovin\'.

Some GigaStudio user here says \"Gigasampler works better than the GigaStudio\" Am I correct? why should we upgrade? how much its worth? $150?
