Last year I purchased a soldering rework station, so I thought now this year I will get my ESR meter. Requirements: Under $100, but useful and reliable. Fully assembled and tested In-circuit (I know … not best way) and out-of-circuit testing Here is a good comparison (although a little dated) http://www.anatekcorp.com/testequipment/esrcompar.htm This one looks really good to me: ESR Micro v4 - http://www.prc68.com/I/ESRmicro.shtml The builder is Russian, so this link is easier to order/ship in US. Some chatting about it: http://www.badcaps.net/forum/showthread.php?t=7394&page=5&pp=20 Old Model v3 mini-review - http://preher-tech.com/esrmicro.aspx Here is a similar one. http://www.peakelec.co.uk/acatalog/jz_esr70.html http://catalog.anatekcorp.com/viewProduct.cfm?item_id=736034 I would be interested to hear what you think of ESR Micro v4 or what you personally use.
