Suppose I have a nice frame with vertical dropouts that I want to build up for general commuting and riding about duties.
I live in Devon but have previously used a single speed. I have a few bits for the frame including seatpost/forks/stem/bars/deep drop brakes but I'm lacking a transmission. I also have some wheels (36h handmades or Mavic Akisum both with Shimano freehub)
I did some adding up for parts costs. Using various online places looking for goodish prices of new bits
For a nice compact double with Ultegra shifters it was something like 520 quid, which is a bit more than I'd like
Fixed was 250, mainly because I'd need a Eno hub wheel built. I've never ridden fixed.
1x9, single chainring at the front and a wide range 11-34 MTB cassette at the back was 175. This would be better for load carrying
The cheapness winner was single speed freehub, 85 quid.
I am thinking that 1x9 looks good
