i had u same experience too, i love violin guitar so much so i wait for long time until some one sell a used guitar than i go for group lesson, its not what i think so easy, there's classical guitar acuostic guitar i buy acuostic guitar but the wrong one the string is too hard, so i spend 180 dollar to buy a used guitar spend 48 dollar to change all the string tune up , 60 dollar for group lesson, but i find out that its very very hard, i cant even catch the chord with the right string it's impossible even just to play a chord or scale , so if i were u , u really want to try u can buy a used violin , dont buy 2 expensive one
now end up i cant do anything with my guitar it's a collection of my stuff now , even i had piano knowledge, so if u really want to try go for it, but piano is much more easiler at least u dont had the press the rit string to get start good luck
