Is there something else? It is extremely useful and simple to use.
The Diablo 2 price check tool.

Right now, all updates have been paused. It looks like Ladder will be here in short order, but for non-Ladder prices you can follow this general rule: High value items are going to be worth more as time goes on and low value items are going to be approaching worthless as we get close to Ladder launch. Players have lots of runes to buy stuff, they have already found/traded for the low value gear they need, and the only things worth buying are still hard to drop (Griffon's, DWeb, Ber, perfect roll eth Andy's)
For instance, everyone is saying that Ber rune is 30 Ist now, which is 10% above the December price. But if you look up a 20/15 Griffon's, it's still going for about 4 Ber - which is the current price in the tool. Now will it become 5 Ber or 6 Ber at some point? I think yes, it will happen but that's just what happens when you have an item that never degrades in value and the currency in the market continues to accumulate.
Also, when I say low value items will be worthless at some point - does not mean no one will ever want Jalal's, but no doubt you could pick it up from someone cleaning out there stash for PGems now. And if you want to sell your Jalal's at this point, you will have to take what the market will give you because if you don't then you will just sit on it.
We are doing our Q&A of the pricing tool now, so if you all have any feedback of things you'd like to see then please let me know here, in Discord, or PM.
