Powerbuilder Training Courses?

Hi, Sometime back I had posted a article requesting some info on Powerbuilder. Thanks a lot for all those who responded. I could get some material from Powersoft about their software with the address I got from the replies. They had mentioned that they have some training programs on Powerbuilder. I would like to know some opinions about their program from those of you who had attended it, or heard from someone who had attended. I just want to know what is the course content like, and the general quality of the program. Is there any other organization offering training courses on Powerbuilder? Also anyone out there knows about any books on Powerbuilder like the ones you find for Oracle etc. Thanks a lot in advance. Please email your responses to nrr@mpd.tandem.com or you can post them. Thank you once again. Bye. Best Regards, N.R. Ramesh.
