The battery scopes like the siglent 810 and hantek's don't see to get the best reviews and I have no use for their multi-meter side. A fluke 125b could be nice for at almost $4k, hard to justify for this.
Thanks for all the replies.
I'm currently considering the AEMC 407 clamp meter, with their free bluetooth software it might get me close enough to what I'm trying to find, at least it has some THD functions. I'm not 100% sure it'll get to the higher frequencies that might be in there but for a bit over $500 could be worth a try.
Another budget alternative is the uni-t 81b portable scope which is CATIII 600 but keep in mind it hasn't got isolation on the inputs jacks and some come with glass fuses

AEMC 407 clamp meter does "Individual Harmonics (to 25th)", so I would think that means 60Hz x 25 = 1500Hz only? So probably won't show 5kHz.

I'm not sure, Specs say it displays to 25th, but the android app for the 407 and 607 models has a picture showing higher harmonics on a graph so maybe it senses them but just can't display higher than 25th? It does say the hz setting goes to 20khz but I'm not 100% clear on if it'll show me data up to that in the app, can't seem to be able to open the app I downloaded without having the unit in hand. I like that it appears capable to check THD on current and voltage.
As many had pointed out, the easiest & possible the most bang for buck is using HV differential probe. As probing mains related devices will be very comfortable, an example scope that was probing the mains line that powered the scope it self.
Also many pointed out, battery powered scope is not always a suitable one for probing lethal voltage.
An HV rated portable scope is as suited to probing high voltages as an HV rated differential probe. In most industrial cases the battery scope is the better solution.

Dave, nothing against your post there, infact I do own a Tektronix THS710A, apart from that clumsy DS1054Z bench scope + HV diff. probe.
Its just my response to OP which I see he just started on this matter, and there is nothing wrong on a bit cautious at spending big bucks, especially at early stage in venturing in this HV probing domain.
Looking at current HV diff. probe's price, imho, is an ideal starting point, rather than have to jump directly buying an expensive "decent" handheld HV isolated scope.
