Where can I buy some small wire ( about # 28 to 30 ) that has the enamel

After checking it out, it seems that it needs to be heated to almost 400
deg C and when I tried that, it did not do all that well.

Google for 'solderable magnet wire'. Amazon has some, Adafruit has this:

I'm using 350°C iron and pushing the cut wire end to the solder blob
nicely removes 1-2mm of coating.( Don't breath the smoke.)

How trustworthy do you think items are on Amazon?

I have had several negative experiences:

A 15" LCD monitor that I bought had a power supply that had no
registration marks on it at all. Taking a closer look was entertaining -
the power cord (also uncontaminated with UL/CSA/CE marks)) had a two
prong male plug going to a three prong computer style power female
socket. If you flexed the power cable at either end the insulation
covering the wires pulled out of the corresponding plug ends...

Another item of inferior quality quality was a LED night light that had
the metal threaded portion come up about 1/4" above the edge of the
socket - nice shock risk!

I would expect magnet wire sold on Amazon to possibly being poor quality
clones with insulation that probably doesn't meet its own "specifications".

If it isn't sold by a company with a physical address then I would
consider it too risky...name brand product means little, it is the
dependability of the company selling it that determines if the product
is counterfeit or not.

There is a lot of crap out there being sold to an unsuspecting public.
