From what I have noticed in these boards, you have a following trends that may lead to indecision about what to choose:
Filco: EK carried Filco, helping create the illusion of them being insanely top notch. In reality, any proper quality control procedure will make any product seem amazing as they weed out the duds. Filco now is rare for some of us (US) or overly expensive, so its talked about a lot.
Leopolds: EK new thing with an extremely illusive release date. As it stands the words "end of march" i.e. The end of the month of march i.e. its last day being the 31st, seems like an impossible concept for people to grasp, so that creates a lot of chatter.
DAS: People who have them, love them. People who hate cleaning, detest them. People who think that 10 keys are made for mutants, also hate them.
All other brands: have not seen enough trends about them, mind you, I am relatively new to these boards, but like you, have spent a lot of time recently fishing for information, opinions, and testimonies.
Your selection of a DAS is solid far as a mechanical board goes. Preferences will be the only legitimate reason to stop you from buying one. A friend of mine has one, and she likes shiny ^_^
