I've been in this game for many years, owned many skimmers, starting with one powered by an air pump and a block of wood
The Vertex 180i that I currently own is the most trouble free, easiest to service skimmer I've ever owned. Set it and forget it, dump the cup once in a while... I disassemble and clean completely every 6 months, and the Vertex is simple to disassemble, and comes apart COMPLETELY for cleaning and service.
I have never owned some of the truly expensive skimmers... not that Vertex is cheap, but I can't comment on anything higher end that what I have. I ran a super reef octopus on my prior tank. Worked pretty well, rarely needed adjustment, but it was impossible to clean.
The 180I is a bit oversized for your tank, but I have a friend with the little 130, and it runs just as well. I'd say that any in the Omega line is going to be similar.
Skimz makes a pretty good skimmer, as well. I don't own one, but have several friends that do, and they all perform pretty well.
