Buy ONCE - cry ONCE.
It's so easy to buy an "inexpensive" tool and "making do with it".
It's like using a dull tool - more effort, more aggravation, more
time, and often not even an acceptable result - to say nothing
of the often associated injuries.
I think it was Walt Akers who wrote an article about the fact
that all power tools cost at least $1,100. You can buy a $400
model, add another $400 in "uprgrades" over the next few years,
screw up a couple of hundred dollars worth of wood and another
hundred or two in wasted time and frustration. OR, you could
get the $1,100 unit first and spend the time you save using
the wood you saved - to actually make things.
