if you ask me, Yes.
there are many cheap ones out there on the market. ( for me that is ) but you are prolly from the states?
around here it is 60 euro for decent TKL ( ten key less, no numpad ) from steelseriess 6gv2 or cm quickfire.
once you go Mechanical you won't go back, trust me.
i guess save up for a cheap one. doesnt have to be a expensive one.
