Several stores in our area have excellent rent-to-own programs for string instruments. We recommend The Violin Shoppe http://www.theviolinshoppe.net and Davidson Violins with several locations in the area: http://www.davidsonviolins.com
For online shopping, we recommend Johnson String http://johnsonstring.com/rental/,
Shar Music http://www.sharmusic.com or Cellos2Go http://cellos2go.com
Above all, stay clear of CSOs or "Cello Shaped Objects.” These are underpriced instruments for sale (under $1000), which are a waste of money since a poor quality instrument hinders a student's learning. This is the equivalent to learning to play basketball with a deflated ball! It's better to rent while you take the time to shop around for a decent instrument.
