ducky keyboards are around the $90-$120 range mostly, depending on the model you get. I think they're a great option for a high quality but non-exotic keyboard
Been running Noppoo Choc since it came out, got two of them. Newer Noppoo Lolita Spyder had the same feeling but didn't award being bought. At work a colleague has a Drevo Tyrfing V2, too much LED but it has a good touch too.
