I tried dental floss. It is cheap to make but its tension changes after around 2 weeks and needs to be replaced periodically. These days I use leader tape used in those 1/4" reel-to-reel tapes. This is a formula a friend arrived at after trying many alternatives on his TNT V.
Leader tapes are stronger than normal 1/4" tapes, about the same width as rubber belts. I have been using one on the Micro Seiki RX-5000 which has a very heavy platter. The tape worked very well and has been quite stable.
Search Ebay for "leader tape" and "splicing tape". It cost less than $20 combined and will have enough material to last a lifetime. You do need a bit practice to splice the tape into a proper loop though.
