My "cable elevators" are inexpensive but effective (as far as cleaning up the rats nest) and aesthetically pleasing. Got to eBay and buy some vintage glass insulators. You can even mix and match colors if you are so inclined. Secure the cables to the insulators with some inexpensive garden Velcro (the kind used to prop up plants) or go whole hog and buy some fancy tie-wraps (they'll probably be as expensive as the insulators;-)
Here's a few examples: http://4.bp.blogspot.com/-x2t9bFNfRhk/UCP8DhyeEMI/AAAAAAAAFK0/SQAU3VRU1Bc/s1600/one.jpg
