I have more than 3 years old channel in Phoenix. Big enough to not close it so far. The fee was much cheaper than now, and I have got like +100% channel capacity of my deposit if I good remember. So being early adopter was worth it ;)

btw, in: Settings -> Payment options and fees there is: Automatic on-the-fly channel creation - and I keep this option switched-off for better control (for not being surprised)
