Sadly, both the Alla and Ogaming DB have quite a few things like this. Quite a bit of missing/miss information amoung other things. Ogaming is MUCH better then alla though in terms of how much and up to date the info is. I'm interested in why you were wanting to look it up though since you've already found one and all the info about it is right in the item desc if you examine it.
As for an item price, it varries a lot more then server imo... the lower level the less likely you are to get a high amount. It also depends on what the demand, in terms of jobs, it is. Then of course if it is a job on your side or not (though with that new scribe thingy... but I think that is for PvP servers only since I don't think you have a "black market" on PvP servers) will determine a bit also. For example, I have 2 master 1s up for 10g each, level 20ish I think. They've been up for probably over a MONTH at that price and haven't sold. Every now and then people put em up for lower then me also... i'm about to just sell them to vendor since I can't even give em to guildies.
