My 9 yo daughter is starting violin this week with Boulder Suzuki 
Strings.  she'll use a loaner  for the first couple weeks until I 
decide what to buy or rent.  In some ways, I'm of the school of 
thought that says the child needs to continue to play a musical 
instrument since I have never met anyone who regrets it.  Her teacher, 
though, suggests renting since kids do quit, or damage the 
instruments. 
I know very little about violins, having played the flute myself, so I 
read up a little here on what you all said makes for a good 
instrument.  I looked on ebay at those "cheap ebay" violins people 
have suggested I avoid- there certainly are some inexpenisve violins 
out there sold by Mendini and Great-tunes but they claim they have 
"your" criteria (but make me suspicious since the "buy it now" is $50 
but they say retail is $400) , and the ones that ViolinsLover.COM 
Store sells look pretty decent, according to the criteria set out 
here, but then <

looks pretty good too... 
then I also think of the first flute I owned- not a very good one and 
I didnt' play it well, but that had more to do with the fact that I 
was a slacker as a kid- I played it well enough, considering, but oh, 
did I appreciate my good quality flute when I got it.  My daughter 
will outgrow this violin and if I can save half the cost of renting in 
the year or so she has it, well, it isn't a bad deal, I suppose. 
so- will I hate something I get off ebay?   I'll certainly understand 
if no one wants to talk about their cheap deal from there online, so 
feel free to mail me about it.  :-)
