You mentioned being told to try gaming speakers... I have to mention that I have my kit connected to an old (2000) set of Altec Lansing PC speakers. They are the typical stereo desktop speakers with the floor sub. They have been my drum speakers now for about 10 years. One of the desktop speakers quit working, but the setup is still a little powerhouse. Especially for my living room setup. My band connects to a large Bose PA system, but these PC speakers work perfectly for me when I'm at home.
However, if you do go with PC speakers, spend the money on a decent set. I bought a set of Logitech speakers (can't think of the model right off). They only cost me about $50, and the sub wasn't powerful enough to handle the kit.
If you're looking for a lightweight solution, something like this may be a good option to consider.
