It is amazing what you can find on Amazon in the electronic area.  For common items, you can avoid having to deal with online order forms at places like DigiKey, Mouser and Newark and find them, alot of times with DigiKey, Mouser and Newark as the source, at the same or less cost, with free shipping and delivery in a day or two.  More exotic things, yes, you have to go to the parts houses, but if you need 100 red LED's for 8 bucks, thank you Amazon.

Keep in mind that any of these analog meters aren't going to be anywhere close to the stated accuracy with chopped waveform transformers.

They perfect for a general look see on what the track draw is, yes not as accurate but I have dropped in this one and check it against a digital and the difference is do slight.

The digital meter suffers the same fate with non-linear waveforms, only a quality true-RMS measurement will give reasonably accurate results.
