For rest of the folks, you will be well served by big chain auto store (just make sure they use a microprocessor based tester not carbon pile load tester)

But one significant thing he got wrong is by only testing 1 cell with the hydrometer.
You need to test all 6 cells, as I've had plenty where 5 cells read fairly good... until you run into a dead cell.
OP, I believe I'll bite on this deal. Especially for $21.99.
Amazon only shows their model BST200, which can be had for $31.50 (after 30% off coupon), but this BST 100 model looks just as good... and $10 cheaper.
Ships on slow boat from China (7-32 days), but I'm in no rush for it.
