hi Kelly, can't see you age here but presume you are adult in which case even if you are "small" you should get a 4/4 violin...
there are good cheap chinese on the market, look up the Cremona range sold out of LA (Saga Instruments)...I bought (after 16 years of not playing) one of their "upper" ranges and use it in my new(again) prof. career as a violinist...you can hear/see this fiddle on my sites, on myspace, youtube etc and on my own site (google "billfiddle")....
when i started to play again I played on a cheap chinese worth GBP60.-...
hope this helps and good luck!
ps...as soon as u get the fiddle, change the strings for the most expensive you can afford...THIS matters a LOT!!!!
