Late night info. Cabelas has H4350 and the ever illusive Retumbo in stock, but don't get to excited, the are only 1 pounders and have a limit of 2, shipping charges and $20 hazmat took my cost up to $91.00, I explained the understanding of a limit, but $45 per pound? They sais they understand but they are not flexing off the limits.
Hope this helps someone, I succumbed to the price cause I needed the Retumbo.
Another note, I have heard Retumbo is showing up in multiple places and my guess it is just becoming available due to manufacturers running specific model numbers.
