I used Pill bottles that fit snugly over a base from a bad tubes (open
Filament or broken glass) desoldered the base fromt the tube leads and epoxied
the base onto the pill bottle. Viola!! a very nice coil form for just about
free. If the pill bottles were opaque, it would look very old-buzzardly I
think.
Regarding some of the negative comments about regens, they can be tricky
especially the simpler ones. You just need to keep in mind that you are really
building an VFO. Keep the layout neat, use short rigid leads where possible.
Mechanical stability is important here. Also the antenna is part of the
circuit, and can make life interesting if it is swinging around in the breeze.
That said, they are still relatively easy to build, and can do a surprising
amount of things. There is also a huge amount of information available on the
net and elsewhere. Even SS regens using MFP102s or such.
(Charles Kitchen has a few excellent projects out there)
Build it and have fun...

Plastic pill bottles have excellent Q. Free at home or real cheap at a
pharmacy. Easy to mate with a tube base also.
