What To Do?

On Saturday I traveled with several friends to area music stores. I am thinking about getting the amp up above. Not sure if I should or not. There is a chance that the old band will play again for a praise and worship service. If we do, I will certainly need something to play. However, I hate to get something just for once service. On the other hand, it would be nice to start playing music again, and if I had an amp, then something might come along? Who knows.
