A bigger selection of kegal and ben wa balls, along with a guide on here would be excellent. I do not know what to do for the best when it comes to purchasing another set.

There are a ton of threads on this subject in the archives too. It will take some time to go through all of those individual threads, but you'll be able to draw on the experience of ~years~ of forum participants, not just those who happen to see your thread.
LH can only stock what sells well enough to justify the warehouse space so the number of kegel balls on offer has decreased. I think they're probably doing alright with keeping a decent range in stock, especially for the 'try it out' and mid ranges.
At the 'advanced' end (and some of us start at advanced), there's usually a compromise between size and weight. The rule of thumb is that the smaller and/or heavier a set is, the more intense a work out it gives. My impression is that size matters more than weight for the majority of people. I seem to be the odd one out in needing as much weight as I can get. As small as possible too, but like I said before some of us need to compromise one for the other.
The last I checked, the Metal Worx balls are the best for size at 3.25" circumference. That's comparable in diameter to a 2 pence piece. The goddess ones are a fair bit larger but best for weight. The knots in that cord will need attention for cleaning but at least it's a silicone cord now (used to be unhygenic nylon).
The thing with an active exerciser like a Tens unit is that you'll have to set aside time to use it regularly. Is that something you're likely to do and keep up with? It might be that a short dedicated work out suits you well. Wearable kegel balls are different in that they work passively as well. You can easily add in active series of clenches whenever you think about it too. Just something to consider. Which suits you best?
My rule of thumb for whether a set is working (and how intensely) is how long I can wear them before the muscles feel slightly sore. (That's just fatigue from the work out and will go away quickly if you haven't over done.) Everyone is different in that. My personal outside benchmark is 6-7 hours. I find that anything I can wear for longer won't work the muscles at all. I find that a 3-4 hour set is more psychologically rewarding but I'm not sure if the end results are all that different.
I think regular use matters most, so experiment until you find one that suits your life and how you'll use them.
