Hi
Steck-system is great. In my opinion it offers you a lot of possibilities. But, some times you have to cut/saw some of the parts if you want to make bigger buildings, for example the floor plate.
Since Wesley Myers mentioned Sweetwater: Sweetwater is "my" western town. One of the last buildings I made was a huge saloon (that I didn't post at tricornejock). In this case, I had to saw the floor plates, the awnings and a few other things. To show you what's possible with a lot of Steck-parts, a saw and some glew: Here are some pics.
Cheers
