We use NetVault with two AIT-3 tape changers/autoloaders for archiving 
specifically, and I have absolutely no complaints. 

I'm in a similar situation, too.  We have to archive geospatial data and 
high resolution imagery from numerous projects here.  I've attempted to 
go the optical disk route several times in the past year, with different 
strategies, and each attempt has been relatively unsuccessful, in 
comparison to our current rock solid tape archiving practice.   From my 
experiences here, I'm heavily biased toward tapes.  The longevity and 
reliability of tapes is just incredibly better.
