sat meter for aligning dish

[lost_one]

I'm installing a non-motorised dish with single LNB for 28.2E, but I may want to add sats in the future via motorised/DiSeqc.

I've tried out some of the satellite aligning/dishpointer apps on Android, they look pretty good, but I haven't installed the dish yet.

Is it worth buying a sat meter in 2021, or should I just use the phone apps to align the dish?

If I do get a meter, I'd like to keep it around 100 Queen's notes.

Has anyone heard of, or used one of these: https://www.satellitesuperstore.com/...ters.htm#sf700
