I've read they have made the connector stronger with the new model (the one with the dark grey logo). Anyway, I suppose you can also use some tape or some clips to prevent the cable from moving.
The point is that the Rosewill is much much cheaper, and considering the Filco is amazing and the The Rosewill is a clone, then the Rosewill could be considered to be one of the best mechanical keyboards as regard quality/price.
I'm not sure if I will buy the Filco or the Rosewill. I don't want to feel like a fool for paying more for something that is the same with a different brand.
As regards keycaps, I'll change them as soon as a get my keyboard with pbt keycaps, no matter what model I choose.
