With very minimal effort, you can achieve the same results using the search function,
For D2 there are just way too many stats variations that can make a single item worth from 100 fg to over 200k fg such as perfect Griffs,
If a system like were to be implemented, you would still need to input the name of the item and all the details in order to search for the estimated value of the item based on stats and past sales,
which doesn't really make things any easier than it is now.
Agreed, the Bold part is especially important.
