More often than not, it's cyclists who ask me what my bikes cost. It's usually a DF rider wanting to know what a recumbent costs.
Recumbents cost the same as higher end DF bikes, you pretty much can't find a "lower end" recumbent, they are made in smaller quantities, so they just make the ones with the higher end components. That's pretty much what I say, without giving a real #.
When people press, I tell them what the MSRP is for whatever bike I'm riding and leave it at that. I don't tell them that I've added/upgraded this or that.
