Outside your budget but if you like the low profile of laptop keys but want the comfort and typing pleasure of mechanical keys, the K70 RGB MK.2 Low Profile with Speed Switches has been my GTKB for the past year or so. It's super sensitive and quick so if you're coming from a clunker or membrane keys, there's a small learning curve. However once you're used to it your wrists will thank you, it's gorgeous on your desk and types so fast, I doubt many can keep up. Totally recommend it. Not many reviews online and it is expensive coz of the special Cherry LP Keys but given I'm typing on it for many years to come, it's a worthwhile investment.
