First real/non-rental ski was a decade-old, unused second-hand Volkl G3 Vertigo (from the early 2000s). Then I passed those on to my dad (his skis needed to join the 21st century), got on some free, beat-up Volkl 724 AX4, and paired those with a pair of Volkl Katanas as my fat ski/almost modern ski. That was a 2008 model I think, completely flat with no camber or rocker at all. Then I replaced the Katanas with a pair of Nordica Unleashed Hell, to bring me into the modern rocker/flat style fat skis. I'm still skiing those 724s, but I'm looking at a pair of Moments on the local Craigslist now that will hopefully take most of the time away from the 724s.
First boots were a pair of Nordica Hot Rods. Beginner-ish boots, but they were cheap. Now I'm in Nordica Hell and Backs.
My first tuning equipment was a cheap tuning kit from the local ski shop. It had a file, guide, wax, gummi stone, and scraper. No stones. I still use an old laundry iron for waxing, but at least I have a real set of diamond stones and guides now.
