To a large measure it depends on the size of the work you wish to do.
For jewellry sized work brazing with fuel-only torch may be OK as
stated by others.......anything larger....model engineering
sized....would require oxy-fuel for satisfactory brazing.

As a point of reference, I had no trouble silver soldering loops of 1/8"
diameter SS rod to the back of a 3" diameter 1/1" thick SS disk with a
standard propane torch. I had it parked on a firebrick, which tends to
reflect the heat back towards the work.

Small items, or sheet steel, I have no problem brazing with a turbo
torch, and now that I have two of them,I could probable do larger
items. My favorite though remains silver solder, Several years ago, I
cut the bell ends from 3" bronze/brass toilet flange and 90 deg. elbow
then silver soldered the two together to allow the lower level toilet
to be mounted at floor level rather than on a platform as the previous
homeowner/non handyman had tried to install it.
I have both torches mounted to adapter hoses so the can be fed from
20 pound BBQ tanks so no problem with the disposables freezing.
