Someone in the Comments section estimated the cost to be $900 (router, 3d printer, etc.) vs $1500. Resale value hasn't been factored in though. It shouldn't cost a lot to have it printed by a 3d printing business.
My intention is not to be combative, but I had to chuckle a bit when I read this. The LR-32 kit in the USA is $635, the 1400 rail is $175, and the OF 1010 is $600 - which, at $1,410 is a little bit more than the DF 500 at $1,359!

The only cost from those that is *specific* to dowelling is the 8mm drilling bit plus a workbench enabling easy vertical clamping. Both of which are multi-use as well.
Also, I do not advise the full shebang LR32 kit. What one really needs is the plate and /optionally/ the distancing/joining bars. Rest is entirely optional and often it is better to direct the money to a TSO PG set for the same function ..
The versatility of the LR32 system is such I am a truly sad Festool - as usual - is utterly incapable to market it. It is literally the poor man's CNC for cabinetry. Yet they do not even bundle the LR32 rail instead of the basic one.. Nor do they suggest to pair it with their PGs ..
