oh yea, and by the way that Gliga Grottano?  did anyone else cringe looking at all those shots of the violin resting on a pile of rocks?!  gee whiz!

Good Lord, yes. I would definitely NOT purchase a violin from a seller who didn't know better than to set it face-down in the gravel to take pictures of it. No thank you.

As to the others, the 'GENIAL 1-Oil' Violin Outfit is from a real-live brick and mortar store based in Pasadena, California in the U.S., so if you live in the states, that might at least give you bit more confidence in purchasing it. A quick Google search turned up a handful of positive reviews of dealings with that store. Not a LOT, mind you, but I didn't see anything negative in my brief search.

The other two are from the same E bay seller, yitamusic. They seem to have a very high positive feedback rating (99.8 %) with only 2 pieces of negative feedback (and 11 neutral) out of 1548 over the last 12 months. That's pretty good, I must admit. On the downside, though, they are based in China, so if you have a problem with your purchase, you are most likely dependent on their good graces to sort it out for you. 

One other niggle about yitamusic...their over-hyped advertisement copy raises some red flags for me. In particular, there's a bit about the brazilwood bow that comes with one of the violins that reads:

"Attention: this bow is not for beginners, it's quality is beyond your imagination, and it can be easily sold over 80usd in western violin shops)"

Um..."beyond my imagination"?  Really?  Oversell much? Besides, in a Western music shop, a violin bow with a price tag of only $80 would hardly be of a quality that is "beyond imagination". I am highly resistant to this kind of selling tactic. As soon as I hear stuff like that, I usually leave the store or close my web browser.

Also, there's this little bit of "fine print" at the bottom of the product page:

------------------------------------------------------------------------------

"Soundpost may fall in posting." 

"Buyer is responsible for install it if this happens."

"Bridge is sent unfitted to avoid damage in transit."

I concur with what others are saying: Fiddlerman is probably the *safest* bet. I went with a cheaper chinese violin myself (Mendini MV650) from Amazon, but that was purely because of my limited financial means. If I could have afforded it from the start, I would most definitely have purchased at least a Fiddlerman Concert Violin. I'd be a lot less nervous than I am right now, waiting until monday to hear from the luthier about what it will take to make my MV650 a respectable instrument. Who knows, I might be pleasantly surprised with what he has to say. But I'm pretty sure that if I'd been able to go with a Fiddlerman violin set, I'd be extremely happy with it and not have to be "surprised" to find myself so.  

Anyway, good luck with whatever you decide on, and let us know, so we can share in the excitement!  

EDIT FOR CLARITY: When I said I was waiting to hear what it will take to make my MV650 a "respectable instrument", I'm not insulting it (or at least wasn't intending to). To be honest, it looks beautiful to me, and I'm already in love with it even though I haven't played it yet! I just mean that it hasn't been checked out or set up, so it could need any number of adjustments (a new bridge, sound post adjustment, perhaps the nut needs filing down to improve the string action, etc., etc.). It might not need ANY of these things, but the point is that, by buying cheap like I did, I won't know until I hear back from the luthier.
