243 is near impossible to find the good one, which is noob. h- is OK, but not as good. Around the same price too...
pam127 is also impossible to find the good one, which is also noob. but there are plenty of other random maker 127's out there. prices vary, but noob is like 300+$
pam372 is nice and available, but both the angus and the 'h' makers have major flaws. Its a cheap piece, so maybe get it and play around to see how you like it.
