@dr pepper:
As the first,
thanks for your opinion!
I must "warn" you that this "Hungarian LCM3" meter
is NOT Q-meter if you mean to Q-factor. But it is very simple design, it demands to choose right parts, though, and that can be "tricky", so you must be patient. It is able to measure: L, C, small resistances (resolution up to 1mΩ), ESR, leakage of electrolytes (and bigger value non-electrolyte capacitors), "memory-effect" (or dielectric absorption), parasitic capacitance of larger inductance etc. Originally it is projected as low-accuracy instrument, but people from around the world, especially from Russia, improved that instrument so you can with some patience get 1% or even better accuracy!
I will give you link to original site - it is in Hungarian, so I recommend you to use google-translate to ENGLISH. Hungarian is VERY tough language and even with google translate it is very difficult to get some infos (and, to make things even worse, there are many typos
)!
BUT, I will give you another link to
Russian forum, dedicated to this project! Google-translate to English works surprisingly well! So far there are about 22 pages, but it is very easy to follow it!
I just "fine-tune" LCM3, I'm not some expert but I have quite decent knowledge about it, so
feel free to ask me whatever you want, here or to PM!

@KeepItSimpleStupid (and maybe @dr pepper): There are AFAIK very, very good LCFX meter ("GO-RLC2") - it is quite complicated instrument, and demands a lot of parts (about 100€) and a proper instruments (oscilloscope, at least), but many people that builded it tell it is worthwhile! Maybe that is what you need, here is a link:
