When I made that post I knew I would regret it.

An expensive meter is only useful if you can use it professionally.
Even simple 20$ multimeters have an amp setting, so there is no need for resistors to check the power drain. Make sure you buy one with a 10amp setting and always start with the 10amp and go lower from that (otherwise you blow up the meter).
I have a couple of cheap meters that I keep in my car and motorbike, but I nearly always use my 30 year old Fluke because it is much easier to use.
For 200$ you can buy a very good meter that is practically indestructible and last a lifetime.
