Great idea for a post. Have had great experiences with Mario's, Menards, and with MTH & Lionel directly; and, as mentioned elsewhere, I love Miller Engineering's stuff.
Related question: does the OGR forum have an A-Z directory of all sponsors? I couldn't find one after a brief search.

ETA (after Arnold's good tip): Eric's Trains, Nicholas Smith, and Trainworld have been terrific to work with as well, with particular props to Trainworld for a recent purchase where they called me (on a Saturday morning) to double-check an instruction on the order. Mario's did something similar (by email) a couple months back and, put plainly, that level of customer service changed my buying habits (plus, Mario upsold me in the process; well done!).
There are a few other shops I'd love to plug in PA and NY but, since they're not sponsors, will wait another day.
