Offering my "opinion" but everyone's needs/desires are different... I'll offer my strategy when it comes to stuff like this.
I have several different indicators in different ranges of +/- 5 thou (reads in tenths), +/- 15 thou (reads in thous) and 1" (reads in thous). I have several of each; all imports most costing about 35 bucks each. Each came with a couple swivel connectors and maybe a small connecting beam/bar. As time passed, I made various other beams, mostly out of scrap and drops, to suit different needs and I just toss the collection of beams in a pan on my shelf. Those $35 units have seen daily use for a few years and all are still working perfectly. I test them in various ways each time I bring-out the granite slab...
If one breaks or starts running poorly, I'll take it apart, learn how they work inside, save some little parts and throw the rest in the scrap pile. If you purchase a high end indicator, they can indeed be repaired but, postage to/fro will cost about what you pay to replace with a new one.
Long story short... For 120 bucks, you can get 3 functional units -and making beams is trivial.
