# Best cheap rock tumblers under $60 that still finish a full run Source: https://tumblegrit.com/best/best-cheap-rock-tumbler Publisher: Tumble Grit. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://tumblegrit.com/how-we-pick A cheap rock tumbler can polish stones well. A full 4-stage run on quartz, agate or jasper takes four to eight weeks, so the motor has to run nonstop for that long. The budget machines that work share three things: a rubber or rubber-lined barrel that seals, a motor and belt that survive weeks of continuous running, and a barrel big enough to fill about two thirds with rock. Under $60 you mostly choose between a small 1 lb kit with timer and speed controls and a bare 3 lb machine with no controls but more capacity. Grit and rough in the box save $15 to $30 on the first run. This guide compares seven tumblers in that price band by barrel size, controls and what each listing includes. ## Picks ### 1.
