If you don't find a Thompson you can buy a new model using Thompson's design (with his permission) from Mad Mining. They have a website but I didn't see the new drywasher on it so you will have to call. 626-782-gold. Miner's Depot in Quartzsite, AZ was also going to start carrying them. I love my Thompson and was impressed with the new model by Mad Mining. I saw it at the Quartzsite Gold show and think the improvements that were made to Thompson's design will make it even better than the original. Several other miners at the show that own Thompsons were equally impressed with it.
