Off Topic: Drum Machines

[E F]

Hi,

Picked up an Alesis SR-16 drum machine at a flea market and am wondering if anyone has any suggestions as to what to play it through.
It sounds good with headphones, but what kind of an amp is best?

I was thinking a keyboard amp, or do they make a drum machine amp?

I don't need anything serious, actually the cheaper the better ($40 range?) it's just for use when I pretend to play guitar and annoying my wife and the neighbors.

Thanks.
