Bummer about the Weller, the iron elements alone cost at least 3x what I paid for it, luckily they are both still good. I've been keeping an eye on eBay for good used replacement irons.
I've got several Fluke in the shop but still use the Simpson more than anything for quick checks. My very first DVM was a B&K, still got it but haven't used it in a long time.
I'm a little shy about buying instrumentation on ebay. I usually wait until a Super Fest then get whatever is on my wish & need list(s).

My most used meter is a $4 one from Harbor Freight, accurate enough for what I need it for and so cheap it is disposable. I did put good leads on it though, the RatShack one has good leads too.
It's sad that everyone is jumping to digital meters. The use of a analog has advantages in the proper hands. People are sometimes unaware of the inherent signal problems that could be viewed with a analog that will often be missed by a digital system.
Analog is nice for testing potentiometers and stuff like that, but my stuff gets knocked around a lot, digital is cheaper and more durable. I have an old RatShack analog meter that I use occasionally, but it isn't needed for most things I do.
My Simpson is about thirty years old and still working. More than just potentiometer work but used a lot to look at Vcc rails or pwr supply sources, range checking. Test capacitors quickly or just working through a circuit for proper drops or static levels. Much better than a DVM. Sure the DVM ability to have a better impedance match or load is a big advantage. Each is a tool that is suited for intended usage.
BTW, try doing a RC computation confirmation with a DVM where a good analog will indicate potential problems or improper rise times.
