Thanks Mark.  Your tutorials are great.  Photojoe, I think you can get all you need from tutorials like the one provided here, or at Carrara cafe, or searching youtube, etc. 

I recently decided to get a formal courselike tutorial from infiniteskills.   I probably wouldn't have done it but there is a big discount if you accept delivery through the ipad app (and I assume for the tablet competitors).  For example, I got about 9-10 hours of Carrara training for $9.99.  The general purchase price for disc or download is much higher.  There is a beginners course and an advanced course.  I've been doing a little bit of the beginner's course each night.  In my case, I think it will be worth it to get the advanced course - given the price.  I like it because the courses are organized and flow from one to the other. 

I'm sure the VTC courses would also be comprehensive and worth checking out. I just happened to get the one from infiniteskills.  It all just depends on how organized you want to be.
