I've been hand laying all my turnouts and much of my mainline track using code 125 rail for about the last 15 years and wouldn't have it any other way. Most I build permanently in place, but some are removable such as this L/H #10 that spans two module sections, (excuse the mess, just moved and getting modules assembled back together.
There's a bit of a learning curve in the beginning, like many things, but once one gets the fundamentals down, they're actually simple to construct. They do require more time to build, it usually takes me several days for a build. I've never compared costs so not sure about that, but believe the cost is less than purchasing a commercially available ready to run turnout. Most importantly to me is the level of detail and functionality of hand laid turnouts which imho far surpasse that of any commercially available. There is a very nice selection of castings/detail parts available from Right O Way to build in regular O scale, or if one chooses for Proto48, which can also be used for O fine scale if one doesn't want to change track gauge.
