I have an opportunity to buy a Burr King 200. It is $200. Is this any good for polishing rock, specifically small pieces of petrified wood?

I can't find any testimonials. The company states that it is a "heavy polymer bowl". Also, should I be worried about the weight of the stones (4-5 inch long petrified wood)? Regardless, I'm going to spend at least 200 dollars on a vibratory tumbler, should I just get a Thumlers? The only issue is this Burr king has a 40lb capacity and the Thumler UV-10 has a 10 lb capacity. Which would work better for the 4-5 inch petrified wood? www.burrking.com/catalog/p-100024/models-110-150-200-vibra-king-bench-top-bowls

I'd get the Thumlers. As already stated, the Burrking was designed for deburring metal parts. Probably castings or shell casings in an industrial setting. If you decide to go with the Thumlers, be careful which one you get. They also make a very similar vibe tumbler for deburring metal. Check with Our member John, he can probably give you the best price on one. www.jsgemslapidary.com

To me from what I can see and what I'm reading the Burr King seems to be for deburring metal parts and polishing casings and such. Would likely not be good for rocks. Just speculating.
Thumlers is a good tumbler and so is Lot-o, Viking, and Gy-Roc. I own a thumlers UV-18. Holds about 16 pounds of rock and does a nice job.
No matter which you choose you will only be able to do a few large pieces at a time. There has to be a good mix of sizes from small to medium and large for the tumbling process to work right. Too many large rocks and the tumbler won't work correctly. Some can even be damaged. I.E. a thumlers bowl can get a hole worn through it if a large rock sits on the bottom and doesn't circulate with the rest of the load.
My two cents worth. Hope it doesn't muddy things up for you.

If you go with the Thumler be sure to specify the INDUSTRIAL model. As jakesrocks said, Thumler makes a lighter duty bowl for shining shell casings. The lighter duty bowl will not survive the abrasion of rocks and grit.
I run a UV-10 and have had nothing but good service from the machine for many years. A friend runs a UV-18 with the same experience. They are well made and built to last.
