Thanks for all the reply's everyone!
About the bokeh thing, I like most bokeh, especially if it's unique and sometimes I really like strange bokeh (like my Helios-44 2 58/2) so don't really worry about bokeh, just forget I said it and think more along the lines of it being fast and the FL.
It seems everyone is suggesting the DA/FA 35 and Sigma 30, does everyone think these are the best option?
Just out of curiosity how come no one suggests the DA40 and FA43, they seem like they get great reviews and I quite like the slightly longer than normal FL.
Thanks guys.
