Actually I chose O scale because it is cheaper. But then again I love scratch building too.
I don't buy a lot of ready made stuff even when I was in HO so I don't know about O scale being expensive. If it was I wouldn't do it because I am on disability and pretty poor.
Anyhow, I find it cheap enough.
As for room needed, I put quite a bit into my 4 by 6 foot layout. Including a small yard, roundhouse, resort, lake, waterfall, river, mining area, bunkhouse area, warehouses, and more.
So again I don't know about needing tons of space.
As for the old Lionel or american flyer stuff, yes that can be expensive as most are collectors items.
I work in O scale and for me it is both inexpensive and doesn't take up a ton of space.
Hope that clears up some misconceptions I been reading here.
