Eric Flint - Ring of Fire series (1633, 1634 etc...there is like 8 books or something).
John Birmingham - Axis of Time series (Weapons of Choice, Designated Targets, Final Impact).
Robert Conroy - He seems to do just stand-alones (1862, 1901, 1945, Red Inferno: 1945)
I enjoy the above authors very much.
