from what i've heard, get the le or the se version of the peluso clone (22 47) which are around 1700. some folks say that the pearlman tm-1 is a better sounding clone of the u-47-- they cost about the same.
then again, since those both use peluso capsules and cinemag (or tamura transformers for some pearlmans) you could also probably source some parts and comission a good tech (such as philgood here
to make something similar for your for far less money.
for even less than that, the oktavamod mk-319 pe and/or mk-219 pe have been compared by some users to the sound of a neumann u47 fet, and the tube mkl2500 has been compared to the u48 tube (albeit the mkl2500 only does cardioid). you could grab a new modded mk-219/319pe for about $440 shipped, or a get a used one and have it modded for even less.
