I can't speak for the Syil since I have never seen one. I was very seriously considering buying one until I found the deal on the KX3. I like the fact that the KX3 is purpose built from the ground up as a CNC mill like fish mentioned. Also, the QC toolholder really is a game changer, especially at the same price point as the Syil. While I have not yet run the mill, I have hooked up the changer and it works like a charm. CLUNK and out comes the bit. CLUNK back in. Cool as hell.
I also looked at Tormach, but their ads for a mill under $8K are a joke...no way you're getting out of that shopping cart with a usable setup for less than 10K.
Anyway, as far as the KX3, if you're worried about the factory raising their prices, why don't you contact them and say you'll place an order pending the reciept of my controller? Once I get it hooked up and can post a couple vids of the mill moving around then we can verify it's all in order. You get to lock in your price, they get another sale in the pipe, and maybe in the meantime it will give them more motivation to get my controller mailed out. Everybody wins!
EDIT: Have you checked into the details of importing to NL yet? May be more difficult than it is to bring something in here to the US.
