try monk, I  solo'ed until inferno with this one..

not all is expensive... just shop smart...

if u are new player need patient.. I reach my first lvl60 within 10 days... unless u buy gold/ using powerlevel service, u need to keep farming... I have complete leveling gears, but they are suit best on barbarian... If u interested to play a barbarian, I will give all to u (except Signet ring and radiant star gems), after my both barbarians reached lvl60..

lv 15 u will get through it by pick up magic [blue colour] less buff still gud for low levels , then as u progress u start to get  rares [yellow colour] then at some point u will get low levels legendries, for your weapon try get lifesteal (Damage Dealt Is Converted to Life) which increase survivalbility.
