Pale Grey Eyes

I'm a newbie here, but I think a comprehensive Aussie rarity guide would be an excellent tool for collectors like myself. Since starting my collecting about 6 months ago I've found it hard coming to terms with all of the different rarity lists around the place, and the conflicting data contained within. It's also difficult to really judge what these carts on Ebay are really worth. I mean, when you see a PAL version of Spectravision's Mangia going for over $150 AU, and Atari Age lists an NTSC version as Rarity 10, but no PAL version, it makes you really think twice before bidding! I'd also love to see a standard database format for collectors to use. (One which includes actual cart scans would be ideal) I've been playing with one of my own, and have seen some interest in the same, but I think a common format could be a great thing for comparing collections, and maybe starting up an online database for collectors etc. (OK, an online version would probably have to miss out on images, due to space costraints.) I know it would sure make trading heaps easier, as you could have a list of your wants and doubles, and people could approach you from online to swap without you making the first move. Might save everyone a lot of cash on Ebay etc. I'm certainly willing to put some time into something like this to make it happen. Am I the only one who thinks this would be a great idea?
