I have a crappy 1/2 that no longer will stay tuned, then I have mine that I play.
I would NOT outright buy a 1/2, even if the child stays with it, they will outgrow it and you will end up having to buy a new one anyway.
oh, and 800.00 is not exactly expensive for a violin.
I bought my used from a guy who's kid decided he didnt want play anymore.
I paid 900.00 for it a few years back.
Its a Gliga, closest thing I see to it for sale now is the Maestro Vasile Gliga, but that one is 1800.00, so I either got a really good deal, or it looks like a really good model
of course, since the fingers fell off and got sewn back on it does not get used much anymore. Still wouldnt sell it.
