Thanks for the reply guys, I'll have to check out the extended warranty - if I find details I will post them on my youtube video... 
  
Yeah I'm not sure why they keep blowing out, I figured an electrical over current issue.  But next time (hmmm, in about 9 months) I'll have another fail and try the X7LL version. 
  
By the way, I can't see the link to my video in my original post.  Were you guys able to view it? 
  
Thanks, 
Mike
