When you buy into the future with the latest implemented standard you are gaining maximum use of your investment.Yes, buying now. But why not a 3.0 ? Cheaper, and I don't plan on ever needing more than 100 mbits.
If you want to do otherwise that's your choice. Looking around for older equipment, maybe used, is not my cup of tea.
DOCSIS 3.1 - 10 Gbit/s downstream and 2 Gbit/s upstream
DOCSIS 3.0 - 1 Gbit/s downstream and 100 Mbp/s upstream
I have a DOCSIS 3.0 modem, purchased 4-5 years ago. So that's where I'm coming from. Today, it looks like a better investment is 3.1. It comes down to the manufacturer, how well the old and newer modems perform in a wide range of applications. Support may be important upfront. Say you buy used off Craigslist. You don't get a connection. Will the ISP and manufacturer stand behind used equipment?
Pick the manufacturer carefully. Check reviews and forums for big issues.
