Yep, there are a several options and and various price points. And there's more to come. I already mentioned the new body Max is working on and fellow member Spencerleehorton seems to be up to something, too. The first I hope will be in the BeesNeez price ballpark, the second will be in the Equinox territory I guess.
If we look at what's currently available and arguably appropriate I come up with the following, more or less from top to bottom price wise:
- Flea. Relatively expensive, but high quality and a very close replica, especially since the headbasket was improved. The number one choice for a reason.
- Ami (was Flea actually*, last time I checked).
-Telefunken USA. They make their own bodies now. There have been some remarks about the quality of the metal work and plating in particular. It's a reasonably convincing copy, though, with pattern switch and all.
- BeesNeez. Lower in price point than all of the above and sturdier to boot. And with the current discount it's actually not so very much more than the Equinox.
Not an ultimately close copy with pattern switch and such. A little more personality, so to speak, especially when a different color is chosen (standard BeesNeez colors at no upcharge).
-Equinox. No pattern switch, but a pretty convincing looking 47 actually. Though not quite of Flea quality IMO, e.g. the headbasket does look smoother than the more expensive Telefunken.
-Alctron GT-2B/Nady TCM1050/T-bone SCT700. This body is actually a complete microphone, but in this case it will be gutted. Price is about half the Equinox.
Some may not know and others may have forgotten, but the MK47 kit was made to fit this body.
Edit: *Not so sure anymore, for the (whole) U47 body that is. E.g. the AMI headbasket is a lot cheaper than the Flea.
