The Quasar line isn't my cup of tea styling-wise, but Colibri makes solid accessories overall. Should be good to go if you like the designs.
That being said, the Quasar line is quite the jump into the deep end right off the bat, price-wise. I don't have any good recommendations for desktop size humidors (<50 stick capacity), because I don't put them on display, and I have way more than small desktop humidors hold.
If money isn't an issue, go for it. If you're just wading into the water, maybe some others can chime in with cheaper options for the humidor that still look good.
As for cutter and lighter, there are also cheaper but very solid options than the Quasar table cutter. But again, if you don't mind the price and want to have the Quasar aesthetic fo display purposes, nothing wrong with them.
Edit:
My own personal humidor setup is a KingChii 16L electric heat/cool humidor (100 stated capacity, but more like 75ish in practice), which was free from a friend, but only $150-$170ish on Amazon. It works very well with Boveda humidification packs. There are other electric heat/cool brands/models that are comparable and have slightly different styling as well.
Beyond that, I store the rest of my collection in tupperdors. For a slightly cheaper but still classy cutter if you don't go the Quasar route, the Colibri SV is solid, and still gives you both V and straight cuts. Lot more options in lighters, and ashtrays are whatever.
