A tipro matrix keyboard is about 1kg if I recall correctly, consider something on the line of 2kg, that should help you to determine the shipping costs and hopefully you will not pay as much. The one shown here has a PS2 connection, make sure you have a 32 bit windows or you won't be able to program it.
I'm currently typing on one (a more recent model but same layout), and have to tell it's a pleasure. To know you can program the layout as much as you want, and on 4 layers is awesome ! The board in itself is very solid as well, and provides all the necessary keys and more while remaining compact. Amazing board for an amazing price. The software (changeme) is free and is really easy to use. Look for the topic "programming a tipro on the fly" at deskthority to find some useful info about it.
But keep in mind several things if you want to go ahead :
- You will need to get used to it. A matrix layout is nothing as a usual keyboard in terms of key placement. You will make mistakes from muscle memory for sure at the beginning.
- The board comes with cherry blacks. Get prepared to mod it if you don't like them. It's plate mounted, so desoldering is required.
- If you wish to change the caps, you will need to find mostly 1*1 caps but certainly a few 1*2 caps with 2 mounts. These are almost non existent in the market, grab some at GB round 4 (deskthority) while you can.
