Just to put in my twopennerth.
A beginner to carving (the assumption being shaping a reasonably sized piece of wood - not a tree trunk with a chainsaw or a tiny netsuke), is easily tempted by the tool kits of 6, 12 or 18 different profile chisels. After all, most of us are easily seduced by nice shiny tools.
However, it is an absolute certainty that the vast majority of those tools will rarely if ever be used and someone starting out needs only 2 or 3 decent quality chisels to produce acceptable first results and thereby learn whether carving is something to be further pursued or not.
(My golfer first attempt, inspired by a Peter Berry article was with a 1/2" bevel edge chisel and an old 3/4" std gouge plus a scapel and penknife for the fine detail. Not easy with crap stringy mahogany but enough to know I had an interest.)
If carving is not for you, then those tools are not wasted as they can still be usefull in general woodworking occasionally. If the craft becomes a passion then you buy tools individually to suit your perceived needs.
It is definately possible to carve with cheap (and homemade) chisels, you just need to spend more of your time sharpening and even more touching up the edge whilst working (that's the secret whatever you use anyway), but surely the reason to carve should be enjoyment and with good steel it is a much more pleasant experience.
I have a sizeable range including Addis, Pfeil, Henry Taylor, Ashley Isles and several others and in common with the other carvers I know, the majority of the work is done with no more than half a dozen chisels.
More important is sharpening equipment and the skill to use it as well as a reliable method of workholding.
The only othe thing I would add is that despit me saying try any piece of wood which looks promising, it is better for a beghinner to start with lime, basswood, fruitwood or even a decent bit of pine as very difficult wood can give a wrong impression. The mahogany I used could easily have put me off and my next attempt with lime was a revelation.
