If your not wanting to wait till you get the books, one option would be to examine some of the dealer sites (I frequently use Tyrus', Andy's, Spragg's and Pushkin's sites to see what is new andtoguage prices. The value's are not set in stone, when making a trade there is a lot of grey (as Iam sure you are aware). What do you have available, I have some illegals in my trader box. If you post here, you'll probablyget plenty of assistance. If you are a CCGTCC member, then you have access to the club library which contains the various books referenced above. If not, consider joining, it is a great group (trust me, they will be there for you when you are at your lowest point). If I can beofany future help, please ask.
