Personally, I think whammy bars are overrated, and they're not advisable on lower end guitars since they go out of tune easily after use, from what I heard lah.
My friend said if wanna get a guitar with a whammy bar, get one with a locking system, like a floyd-rose or something, yes a b**** to tune but it stays in tune better when you use it.
But the problem is, a guitar with a properly working whammy bar system that stays in tune costs way more, in the 4 figure range. Those bridges alone cost more than my whole guitar, almost twice the price!

My cheap squier's whammy, I seldom use, and even then I've already messed it up and caused the screws to strip inside, but luckily managed to get it out. If it breaks inside, I would have to spend a lot of money to get a new bridge, maybe 3 figure sums.

A slight 'bent' with the whammy bar when you use it enough of times, would cause it to strip the screw holes inside and you might never be able take the whammy bar out again, without grinding and getting stuck halfway out. At least get one that does not screw in like the typical strat, it really sucks!

For simplicity sake, I think I should've bought a guitar with a fixed bridge instead.

But never mind, I locked down my bridge already, so all's fine there.
