The Burdens of Being Recumbent

About five years ago I got my first recumbent bike and became attached to the comfortable and speedy way these things operated.
Back pain was minimal, you were pretty much out of the face of the head-wind, and you could practically ride all day on these things.
Sadly though, I've slowly begun to realize how difficult it is to obtain parts for these things.
The current one I've had I've been riding for a little over year now.
It rides like a beast when it's working properly, but when inclement weather or road conditions hit it, parts wear down quicker.
The typical response is to go to a local bike shop and find the correct part for it.
Install it, test it and then you're pretty much good to go.
But that really isn't the case with recumbent bicycles and the primary components of shifter cables, brake cables, and the chain which are all longer than that of a normal bicycle.
You call around to different shops and end up eliminating them from your list due to them not having it.
Sure you could order these types of things, but when you have a job like mine, that isn't really a good enough option.
You order them online and then you're not riding your bike at all until 2-3 weeks later when you're finally able to swing by the house or wherever you had them delivered to.
This excessively long delay in ordering, shipping and transporting takes what should be a healthy activity and turns it into nothing short of uncapped anger and a heart attack waiting to happen.
Why places don't stock just a few of these parts and instead cater to the masses, I don't clearly understand.
Surely they just can't order a few for those oddities that happen to pop up every once in a blue moon?
In the meantime, I'm really beginning to weigh the decision of using a recumbent as my primary bicycle/means of conveyance.
Especially in the midst of surprise breakdowns in an area with limited supplies, I wonder if it will be worth it to just switch back over to something more commonplace.
