I started speedcubing last year at around my first comp which was October. I first solved the cube in June last year (2014.)
I have 90+ puzzles in my collection.
See
http://youtu.be/FLEdyb8ogUk for my setup. I know I really didn't go over my cubes but it works.
If your wondering why I have so many, is because I work and get paid some good money. I mow my parents lawn which is about 2 acres, and there are 2 halves. It takes me about 3hours to do. 10$ per side.
The other thing I do is work at my uncles restaurant booth (every year) during a festival in NewburyPort, MA. I split the tips with my cousins (that also help out) and get paid $9 per hour. Last year I got about $300 out of 5 days. This year I got about $300 in about 2 1/2 days.
Most of that is in my savings account for when I want certain puzzles.
Also, most of the big cubes (9x9-11x11) we're gifts or added up money from gifts to buy them. This might sound crazy, but I have bought all of my cubes with my own money, and barely any of it was my parents. Except if they were a gift for like my birthday or something.
