manometer for vacuum

Hey everyone i cant seem to find a manometer that can read as low as 15 microns. If anyone has any advice on where to get one it would be quite helpful. It also needs to be affordable nothing over 100 dollars

A McLeod gauge is one option. You might be able to find one on eBay for a reasonable price with enough patience.

...stressing the patience part...and then there's the mercury...
...there's a lovely, interesting $201 buy it now item in 0.01 mm graduation on ebay...McLeod gauge in the fuses section...the kind one really wants can be found at labx...hint labconco...still probably not $100 or maybe even $500...just buy a Yellow Jacket or UEI electronic gauge in the end...
