I find the sales history part of the database very valuable, however, the graph isn't very helpful because it seems to be sorted by ascending order of price, rather than time. The value of these jets seems to increase quite a bit after they sell out, so knowing when the sales were transacted would be great.
Also, more data from outside waffle and diecastairplane would make it more useful. One way to do that would be some way to add ebay transactions that match the model number. I know the models available on ebay isn't an exact science, so maybe users could add ebay item ids, and the system could retrieve the sales price for that item id.
