Re: Drum Throne Broke.
Well, not sure what you should do with your sister, but it sounds like its time for a new throne. If you have sufficient amounts of money, a good throne will run you between $135 to $200 depending on which one you got.
However, if you have no money, there are some cheaper alternatives. Look at Tama, Yamaha, and Pearl, they tend to have some in that $80 - $130 range that are just like their big heavy ones, just a little bit lighter. The important thing is having the spindle for height adjustment (you rotate the seat to make it go up and down). If it has that, chances are the rest of it is built well. Check out MusiciansFriend.com and look at their offerings to get an idea of what's out there.
I suggest you guys go to IKEA and get a regular chair for that computer desk too.
