Patch Cords?

[Kjarger at aol.com]

I am building a DIY modular, and I am frugal, so I was thinking,What's the
cheapest way to obtain mondo patch cords of all different lengths?  I don't
plan on any patch normalization.

Type       Characteristics

1/4"         Shielded. Great Quality, $4.00 per cable,  $0.70 per jack.  
1/8"         Shielded. Wear out, break easily, $3.00 per cable, $0.50 per
jack.
PIN          Unshielded,(I want shielded) $1.70 per cable, $0.60 per jack
BANANA   Unshielded, ("), $1.70 per cable, $0.60 per jack
RCA         Shielded, Unknown lifetime?, $0.75 per cable, $0.25 perjack

Costs above are estimated  in quantities of 50 pcs. each item, because you
might build your synth over a long time span.

 Based on the above estimates, for each modular patch system for 200
connectors and 100 cables the cost is:
1/4"          $540
1/8"           $400
PIN           $290
BANANA    $290
RCA          $100

I got the low price on RCA because the cables are made by the billions and so
are really cheap, and the jacks are available from closeout houses in all
sorts of 8X8 and 9X9 type matricies,  with all the Jacks mounted on one PC
board.  

Here are my ideas for Using this RCA system:

I think the PCBA mounted jack plate would be no harder to install than the
same number of jacks....the PCBA feels pretty sturdy....If the matices are
too tight for your fingers, you could remove every other Jack in high traffic
areas.  
You get stereo cable pairs from closeout houses in 3,4, and 6 foot lengths.
 You gently "rip" the stereo pair apart (ask if this is possible before you
buy!) to get two cables cheap. You could put colored electrical tape ($20 for
5 rolls?) on the area of the RCA Connector you grab, to ease grasping, and
allow identification. 
 I played with some of these items, and, by expanding the connector's outer
ring and/or contracting the jack's inner ring, you could actally tailor the
feel of the system to your comfort level.  Also, you could "tighten" the
connections as they age. I think that quite a large surface area is present,
so I have trouble imagining problems right away, but what about long term?
 (Note: I'm just a hobbyist, the synth "repatching" will only be used at
about 1/10 professional use level.)

Stop Laughing!!  I know what you're all thinking, but it is a big savings
which you can spend on the active elecronics!

So what do you think?  Any RCA experiences? Anything wrong with my estimates?
I know many of you would be throwing rotten cabbage at me if you could!
