TDS Meter Recommendations?

Hi All - I'm looking through Amazon and seeing iffy reviews on the TDS meters. I don't mind spending a bit if it's reliable.
Any recommendations? Do any of the multiple testers work? Would be nice to get PH as well as TDS, but most importantly just want an accurate TDS for quick tank checks.

This one:
HM Digital AP-1 AquaPro
https://www.amazon.com/gp/product/B007KDYOMU/

and at the same time be sure to buy this:
HM Digital C342 TDS and EC Calibration Solution
https://www.amazon.com/HM-Digital-C3...dp/B001VE99X8/

Even the best TDS pen is arguably meaningless unless it is recently calibrated. This new HM Digital pen is excellent and I think probably the best that you can buy within a sensible price bracket.

I got this one https://www.amazon.com/dp/B002C0A7ZY...p_mob_ap_share
It was cheaper because it's purple. I got because I didnt think my other was right. Even though I calibrated it with the 342 solution. Both match prettty close so now I got 2

Few reasons it is cheaper, but don't think it's because of the colour!
- calibration is via a small screw which is much more fiddly and less precise than the digital method
- accuracy is +/-3%, rather than +/-2%
- no temperature compensation

The above may or may not be important to you, but for an extra $7, I would really recommend the newer AP-1 model (it's still an absolute bargain at less than $23!)
