Ok, Tim, I'll give you the opportunity to talk dirty.
I need another really good saucepan for making more delicate sauces; even heat is the king here, but responsiveness would be nice too. Heat capacity is not needed.
This is really easy for me to say, but:
I've been cooking quite a bit with my 2.5mm Mauviel saucepans recently and have become very aware of the superior heat distribution of the thick copper. 1 1/2 cups of sugar for salted caramel was significantly easier than the same dish a few weeks ago in Crystal Fouch Ware, sarcasm intended. It's easy for me to say because I paid $39 for the 2 quart Mauviel nickel lined 2.5mm copper chefs pan at Zabars in the late 1970's. The 3 1/2 quart 2.5mm chefs (tin) was $50 on sale at Wellborn-Senora's about 20 years ago.
Then there is my magic $20 1 1/2 quart de Buyer 2.5mm aluminum (stainless lined, copper sheathed) with an additional 2.5mm aluminum disc on the bottom - TJ Maxx closeout.

At today's prices, there is no way to justify the expense of the copper or even Deymeyere. The answer may be the second hand market or copper, if that exists. You might also want to try some higher quality cladded pans like Mauviel's MCook. If you get to NYC, a search of Zabar's might just find you an old saucepan bargain. The other option is the higher quality All-Clad, I mean All-Clad Limited, the thickest, most even-heating All-Clad. (Crystal is now gagging!)
I do know there is lots of 2mm copper ware that is showing up at TJ Maxx and Tuesday Morning. I used to hear that it was not worth buying but I suspect that it may perform decently. Maybe, somebody has experience here.
If even heating is the primary goal, a solid aluminum diffuser should improve the performance of your inexpensive Jiffy Pop pan. Just think, even heating and instantaneous responsiveness on your Hotpoint.
I probably have not helped you at all, at least I've given Crystal some ammunition.

ps: There is one caveat about Zabars which can cause problems. The best advice is to seek medical assistance after four hours...
