Many thanks for your encouragement, Jamie...but I have just looked through your own topic (on Ellerby) and am not sure which emotion I feel more: awe or even deeper depression!
Seriously, wonderful inspiration.
I feel (like you?) that life is too short for building my own track and sorting things out to EM or finer scale on the size of layout that I am building (and have been for about 15 years!), so stick with OO, RTR - usually modified in some way - and kit motive power and stock, but buildings simply have to be scratch-built.
I am about to start on my winter project of a William Tite-style station building. See Axminster, Topsham, Whimple as they were, or several others on the LSW/SR western section to get the idea - and the challenge presented: gables, rooflines and chimneys galore!
Mike.
