I've had this Filco with cherry MX brown switches for about 2 month now and so far I like it far more than the logitech keyboard it replaced.
As oliver said it's probably best to try one if you can.
The lack of features was not an issue for me, nor the basic design and if you can get past those the typing experience is much nicer than that of a rubber dome board.
Whether or not a nicer typing experience and excellent build quality is worth £100+ to you is a different matter.
I'm glad I bought mine, but can't help thinking its not worth quite as much as I paid for it, however money permitting I'd only replace this with another mechanical keyboard.
