rush evo is the newer version of the rush. if you were gonna get one of those i would not reccomend it but i do recomedn the firestorm which is like the upgraded version of the rush evo. if you buy rush evo its probbalby gonna be second hand and even if you do get it and it works well then youre gonna have a hard time finding parts for it[&o]. so i would go wit the firestorm if youre thinking about buying. check oiut the firestorm forums
