Electronic Soil Tester Recommendations

[resolutejc]

Hi all. I was wondering if any of you have had any luck with electronic soil pH testers? The reviews I have read for the $5-15 dollar testers haven't been so promising, especially the Rapitest brand which seems to dominate the market. I am not interested in taking my soil somewhere to get tested. I want the convenience of doing it at home myself.

With your recommendations, hopefully I will find a reliable tester ($10-30) that provides accurate results. It would be great if it was multi-functional too, I.e. testing N-P-K levels too.

I am an indoor container gardener.
