T204 prices
 

I'm thinking of buying a membership to the Vintage Card Prices site, but I'm really just interested in researching the sale prices of T204s and specifically looking for variation in the prices of commons. Can anyone tell me if they have enough T204 data for this to be worthwhile?

There is some data, I'm not sure what you feel is worthwhile... I'd suggest getting a day pass for 3.99, look around, then decide if you want to subscribe.
