I really like the Korg Pitchblack series.
As accurate as any these days, LARGE screens, multiple display setting options, 9v out.
I used the PB-01 for almost 15 years with really no issues or complaints.
I recently "upgraded" to a still discontinued, yet newer, korg pitchblack advance.
This one is more accurate but also has a larger screen than its predecessor.
One feature i love about the PB's is the angled screen, making it easier to read when you're not on top of the pedal.
Their newest series is "even more accurate" but loses the angled screen. Theres also an option with no button, and a "bass specific" version that has a wider freq. range it can pick up.
The PB-01 and the PB-AD (the older 2) are still top tier, and go for under $75 on Reverb. The PB-01 I've seen for as low as $20
