I think, in a few years, when there's more LCC railcom detectors, it will make sense. You'll be able to use a CS-105 and run your railroad, basically replacing JMRI for most functionality.
But I agree that, today, it's not priced very competitively, even if the pricing is in line with development costs. I live in a Digitrax+JMRI world, and it will cost me over $800 to replicate my current setup, and despite owning an entire LCC signaling system, the only advantage I get today is that it will connect to my home WiFi, so I don't need to connect to a LnWi or boot up a Raspberry Pi to use my phone as a throttle.
In all honesty, I'll wait for reviews, and probably pick one up for my next layout. But for now, my T-trak modules can survive with a DCS51.
I grew up in the 215 area code (the same area code as TCS's phone number) and I'm always happy to support Amercan made, but supporting a company this local is even better.
