I once searched for the internet for the "best toothbrush" before I went and bought a new one. Looking back, that was silly. That is not something I need to research so heavily before investing. But Rock Tumblers... Rock tumblers are something you might actually want to take some time on and make sure you get the best bang for your buck. They aren't a commodity item like a toothbrush and picking the wrong one can be a disaster. You don't want to put a bunch of time into polishing a batch of rocks just to have the motor give out on you before you make it to the final polish!
In this guide, you will find the best rock tumblers for the money in 3 different price ranges. From under $100, to mid range $100 - $200 stone polishers, all the way up to high end rock polishers that break the $200 mark. You will find out which units perform the best in each category and will hopefully give you the most bang for your hard earned buck!
When you purchase a rock tumbler for over $200, you can expect to get a large capacity of up to 12 pounds, as well as a high-quality metal barrel construction that will last a very long time. The more expensive rock tumblers like these do not need to be replaced for many years, so you won’t need to worry about having to buy another one anytime soon. You will also find that rock tumblers over $200 usually have multiple barrels, which will allow you to polish rocks in one, while doing different stages of grit in the other. This can greatly speed up the time it takes to polish a batch of rocks.
A lot of these machines have a rotary design as opposed to a vibratory one, which results in much quieter overall operation. The best rock tumblers in this higher price range also usually have a thick rubber barrel, or at least one that is rubber-lined so that the rolling sound is minimal.
The motors on these units are also usually of higher quality and these will be machines that will last you a long time and go through many batches of stones.
The Lortone Double Barrel 33B tumbler kit has a lot of the features you find in the greatly expensive tumblers, for a little less money.
Since it is sold in kit form, it includes a 4 stage grit supply (coarse, medium, pre-polish and polish grade grits), a guide book, a small supply of rough to get started, and it even includes plastic pellet media for cushioning during polishing. The rock tumbler itself measures 6.25L x 16W inches and the entire package ships at a weight of over 17 lbs! backed by a one year warranty from Lortone, this tumbler is built like a rock (no pun intended).
This rock tumbler kit is often priced just below the two hundred dollar mark, but I wanted to include it in this section since it is usually right on the border. Since the price is right on the border and it isn't higher in the over two hundred dollar range, there is a slight trade-off. This tumbler is six pounds of total capacity instead of a higher volume like the double 6lb (12lb total) tumbler featured later in this guide. Two 3lb barrels give you a total capacity of 6lbs (hence the name 33B). However, most will find that the six total pound capacity of this rock polisher is more than enough for their needs and this is a no brainer compromise for such a high value rock polishing package at this pricepoint.
The high quality Lortone model is built well and includes all steel construction in the tumbler base. Heavy duty cords and a professional grade motor mean this machine will last a long time. The rubber tumbler barrels are relatively quiet and can be run continuously without driving you crazy with noise like cheaper models with hard plastic tumbler barrels.
If you're not interested in all of the extras that come with the kit, you can also get just the Lortone 33B Rock Tumbler by itself here. However, the extras that come in the kit are a good value as the pricepoint is not much higher compared to the costs of purchasing seperately.

That way, you can do a fine grind in one while running a medium grind in the other. Or polish two types of materials which require different grit medium at the same time.
