(replying to this old thread in case someone reads about this LCR meter) What did you finally end up with?
I own one of these (Escort ELC-131D LCR meter) and I am very happy with it. Price in 1995 was around $450, so if you get it cheap and in perfect working condition, I would buy it. It's quite accurate. Yes, only two frequencies (120Hz and 1kHz), but that's enough for most cases. And I would not recommend measuring in-circuit anyway, if you want accurate results. In-circuit measurements are only for quick-testing if you look at a component that looks broken, but don't want to desolder it for a first test. If measurements are off, you have to desolder it anyway to verify that it's indeed broken.
