Edit:  the Chailly looks awesome too, will come back to that soon.

Wow, these are all wicked good suggestions.  Looking through all of the above, I decided to pull the trigger on the John Elliot Gardner cycle, and the Zander 5th and 7th.

I had to rule out the Minnesota Orchestra/Vanska cycle, as it seems to only be available on SACD. Am I missing something, like maybe there's a way to still rip it to a lossless flac using a standard laptop CD?

The Karajan performance is classic, but I have heard it and didn't love some aspects of the recording quality.

The Otmar Suitner/Staatskapelle Berlin looks pretty sweet, but I am going to hold off and see how I do with the ones on order. I may come back to this one.

Thanks again to all for the awesome input.

BTW, slightly off topic, but a recent discovery for me is the Giardino Armonico recordings of a bunch of Baroque music including Bach Brandenburgs and Vivaldi Four Seasons.  Really something special - here's a youtube of some Vivaldi: 

I just wanted to throw that out there...
