Too bad the K & K Audio kits are no longer available, that would have been a no-brainer.
This one looks interesting though:

Although a little above your price point Audio Note has a nice kit as well:

Hagerman used to have a few more kits but evidently this is it now:

You’ll have to source everything but the PCB for that one.
Bottlehead might be an option as well:
