It's an australian electronics shop (which has ventured to selling pcs and other audio/video goods in the last few years).
not sure if they ship overseas though

Hello Brian,
truth be told, I didn't actually "nip along" myself, but a friend in Oz got one for himself, mentioned it to me and I asked him to get me one in return for sending him some British goodies. I gather that Dick Smith have sold quite a few (12,000) of these ESR meters, and some abroad.

If you experiment, and change the cap resistance value from .001 ohms to even 2 or 5, it really doesn't seem to change too much in terms of the voltage curve, so i don't sweat it 
. the thing i've learned to always measure is a) unloaded voltage on secondaries and b) winding resistance. those have SO much more of an effect.

well, as long as you're within reason with your capacitances, it seems like you don't have to worry about ripple currents. you DO mean the big wavy things before the voltages smooth out, right? i didn't realize that it resistance would have such an effect. couldn't you "tune" your capacitor by paralleling a resistor? or is that folly of the worst kind?
Hi Brian,
If you have an LCR bridge or meter, you should be able to get a resistance from that. More use from one instrument.
You can also look up a manufacturer's spec. from the catalog. I'm sure most of these parts will range close to the same number per capacitance value. I am assuming you will be using new parts for a design. If not you may want to check your parts more closely than the ESR meter affords.
Specs are freeeeeeeee!
