Amplifier for electronic drums?

I am 16, and just spent my ENTIRE life savings on an electronic roland drum kit. My dad has agreed to buy me an amp for them (so that I can practice with my band rather than simply using my headphones all the time) but I have a budget. Guitar center cells electronic drum amplifiers, but they are really expensive. Is it possible that I could use a bass amp or a keyboard amp that says it is good for “drum machines” in the description? this one —–> http://www.guitarcenter.com/Behringer-KT108-ULTRATONE-15-Watt-Keyboard-Amplifier-103643284-i1173577.gc
In response to the first answer: I am not a beginning musician and I’ve played the acoustic drums for a long time, but I had to move them out of my apartment because they made too much noise. However, I’ll really be satisfied with whatever works. I’m just looking for something that will work for practice alone and with two other kids.

To the ears of a beginning musician it is going to sound fine on a keyboard amp. 15 Watts however might not be as loud as real drums (I’m saying I’m not sure, 15 W for guitar is about the same volume as a drumset), but if you guys don’t play super loud or anything I’d say this is going to work for you.
