Let's Talk Arenas of Consumption

Here's the last of my scrapbook pages from my vacation to the Seattle, Washington and the San Juan Islands.  It was inspired by a prompt in Shimelle's Pretty Paper Party scrapbooking class that called for using a border punch.  She mentioned that pulling out a tool like a border punch was a good way to try to get your money's worth out of it. I don't have any border punches, so I pulled out another punch instead.  
The prompt did get me thinking about some of the recent popular tools in scrapbooking that I have avoided:
border punches;
copic markers;
texture folders;
die cut machines;
anything that requires sewing.
In each of these, I've congratulated myself on avoiding a large "arena of consumption" where I could easily find myself collecting one of everything in a given set (and then, too often, letting them gather dust). 
There are, however, many arenas of consumption in which I dabble:
paint;
spray inks;
stencils;
ephemera;
paper.
Over time, I've tried to find my style so that I only dabble in those areas where I know I will use the products.  I'm not perfect, but who is?
So, what arenas of consumption do you enjoy dabbling in? Are there some you now wish you avoided?
