Filthy Lucre

As I was pondering all things railroading tonight, the money issues popped into my mind. I'm a couple of months (at least) from building anything, so it's really not a pressing issue, but still. My anxiety about over reaching goes this far too. My layout right now has 16 turnouts on it, and one lap turnout that is $50 by itself. each of the#5's I'm using is $25 bucks. That's a lot of cash even before I've got the rail to tie them together... or the $500 DCC set up to drive the whole thing.  Sigh. I'm really trying not to stress about this part of the "overreaching" issue, but it's not easy since money is an issue in general at this moment.
