Hi guys. I'm a newbie to logos and just purchased the Scholar's Library base package the other day. I'd be grateful if anyone who started with this package could suggest some reasonable value additional resources which they added to their library and which really benefited them.
I guess I'm trying to get at, are there any additional resources which people see as pretty fundamental and which won't break the bank?!
I've seen on a few of the tutorial videos mention to the Greek-English Lexicon of the NT and Other Early Christian Literature (BDAG) - is this one of the first additional resources I should be looking at?
At this point in time, I'll be using logos to prepare sermons for my church, and using it for my MA in Biblical and Theological Studies which I started back in March 2011.
All recommendations will be gratefully received 
Thanks.
