Hey Sebastian, nice to meet you.
Are you looking just for a Finishlynx solution? or open to other cool stuff? we have bought months ago a CAMERA VIDEO FINISH PRO 2D from VOLA. you can see the specs here.
We used it in one bicycle race (vuelta a Chiloé in Chile) and it works like a charm, unfortunately we realized that there is not enough market in Chile and we are thinking in selling it. I offer it to you before of publishing it on the forum, let me know, I can send you more information and pictures. My email tiempos@timer-crono.com.
It has 1 use, is practically new, comes with all the accessories in the link and software, we can teach you how to use it as well.
Best regards!
