Hi, I just saw this list of useful SCOM 2007 resources so I thought that I would post them here as a reference for us all :)
Course 3386 - Implementing Microsoft System Center Operations Manager 2007 - https://www.microsoftelearning.com/eLearning/offerDetail.aspx?offerPriceId=138307
Course 50028 - Managing System Center Operations Manager 2007 (5 days) - http://www.microsoft.com/learning/syllabi/en-us/50028afinal.mspx
SCOM 2007 SP1 training videos (these are new as of January, 2008) - http://technet.microsoft.com/en-us/opsmgr/bb986763.aspx
SCOM 2007 on Technet :
Good place to see all technical documentation about the product - http://technet.microsoft.com/en-us/opsmgr/default.aspx
I ordered the e-learning collection 3386 about 3 weeks ago (thanks again to Trika), and I've been very pleased with the training. The virtual labs alone are worth the price. If somebody out there is getting ready for an Operations Manager 2007 migration, you should invest in this training.
