If you live in the Jerusalem or Beit Shemesh area, I've used Tzvi Lefkowitz (aka Handyman Tzvi) a few times now and I highly recommend him. He is that rare combination of honest and competent who goes above and beyond what is asked for and yet still charges reasonably. He has come in especially from Beit Shemesh to Jerusalem to fix various electric issues in my apt (a/c, dud chasmal) and he always knows exactly what to fix and how. He is also such a sweet guy!
