Midsouth Shooters Supply has a pretty good deal on their house brand tumbler and sifter, which closely resemble the RCBS Frankford Arsenal units, but a whole lot cheaper.
In all the time I've done business with MSS, they're ALWAYS spot on with pricing, usually a little better price wise than any other retailer. Generally speaking, I save about 10% going through MSS than Midway, but I do shop pricing on both sides of hte table.
MSS site is a little more difficult to work with, but I can usually look up manufacturer's part numbers if I know them, and Midway usually has them posted in the item specifications, so I can be sure of comparing apples to apples.
I do order from both, depending on who's got best pricing.
Both ship extraordinarily fast, both are super reliable, and both are excellent to do business with.
