Ok, so I got the board. Some pics are here
https://goo.gl/photos/7KqCgJS75drbLVKp7. I've put some of my conclusions from a few days of using below.
The scissor boards and laptops I use daily:
- Lenovo X220
- MacBook Pro early 2015, 13 inch
- Lenovo KU-1255 03X8715
- cheap Chinesse scissor board
Layout
The cheap board tries to mimic MacBookPro layout nearly 1-to-1. The "enter" area is a bit different, the rest is the same. The area covered by the keys is exactly the same. Mimicing a Mac layout and then putting PC layout on top of if means sacrifices. There is no insert button, and F11 and F12 need Fn to work. I like that the right alt is near m and , as I use it a lot for Polish characters.
The size of the rows q to p and ], a to l and ', z to m and / is standard and matches all other keyboards and laptops I have.
Chassis
Both chassis of Lenovo KU-1255 and the cheap board suffer bending while pressing keys. In the Lenovo it is bearable, in the cheap one no. The chassis hits the desk if you press the space a little to hard. I'll stick something under it later.
The plastic of the cheap one is not that good, but still better than what you usually get for 10 usd.
The rubber feet are good, the board does not ride along the desk - better than Lenovo.
Button shape
The cheap board tries to make the keys look like MacBookPro keys, but are a little too big, spaces between them are too small. Feeling if you are pushing the right button is much more difficult than on any keyboards compared. The keys have sharper edges than the mac ones to.
The ideal here is the X220 and KU-1255 from Lenovo. Both provide excellent curved keys. I like the newer design more, some of my friends prefer the older one.
Tactile feel, key travel and noise
The travel feels the same in all except the X220 which travels further. The fill is a bit more clicky on both Lenovos than on the MacBookPro and cheap board. The cheap board key feel is very near the MacBookPro except for MacBookPro being a tad softer and much noisier. X220 produces the largest amount of noise, than MacBookPro, than the KU-1255, leaving the cheap Chinesse board being the quietest of the bunch.
Summary
I'll try to use the Chinesse board at home a bit longer. Right now I see why the Lenovo KU-1255 costs 50-60USD. It's just worth it and so much better. I think that you are getting a good deal on the cheap scissor 87 board anyway with 10+something USD. The biggest downfall of it is the chassis (that you can reinforce yourself) and the shape of the buttons - these are too big and sharp and do not let you feel the spaces between buttons as good as the other boards I have.
