Hey man I was in your same position last month. Was deciding between the S1 and the 300mkii. I decided on the 300mkii because portability was more important to me. Also just added some chroma caps, check out my pictures in the controllers sub forum.
I absolutely love the 300 man! Both units are great though :-)
Just read the s1 article, my thoughts and prayers out to DJ solomon's family and friends.
