I read the posts about "bubba" and I wanted to commend the instructor that I had earlier this year in HTown.  His name was Lynn Sturgill and he stayed on topic the whole time.  Even while being bombarded with off topic questions he helped us maintain our focus on the significant material.  Even though he told us there wouldnt be any appendix q's in the code section(in which there were 14), he was very easy to understand and i am sure he stayed countless hours past class to answer questions.  In fact he kept the whole class over 1 hour one evening to make sure we soaked it all in.  Well worth the money!
