I'd suggest buying online from a reputable specialist seller. They do exist. Prices are much lower because they don't have the same overheads as a shop. If the violin is no good, it can be returned. However be wary of buying a wooden bow online. Carbon fibre are more reliable.
If you can stretch to, and find, a Gliga, that is what I would suggest. Another make which has impressed me for the money is the Primavera Loreato.
