best honest answer I can tell you is when you buy cheaper camera's there ALL HIT OR MISS
some guys buy one"X" brand and it works great next guy buys same exact camera and well, its JUNK
cheap camera's IMO< are like pick of the litter, some times you get lucky, some times you get burned
even the mid range cam's are this way
I have owned a lot fo cam's over the yrs, maybe close to a 100 or so, starting from the late 90's
I have some 300-400 dollar cam's that SUCK and I have some cheap 025 buck tasco's that work awesome>
then again I have had two 25 dollar tasco camera's that failed in the past few weeks(just over a yrs use) and have some cam's from the early 2000's that are still working??
so if you follow my point here, ALL camera's seem to have some poor QC happening, till you get to the VERY top tier camera's where they stand by and REPLACE if needed, and you DON"T see many having to be replaced either!
maybe not what you wanted or hoped for in an answer, but honest advice
if you see a local store with a name brand camera cheap, odds are it might be just as good as anything else IMO
or it might NOT!
