You'd have a number or choices around the Denver area, but here's one possible tour (all prices quoted are non-resident weekend rates, so you could get off cheaper during the week. All prices are without cart):
Murphy Creek, a terrific layoud by Ken Kavanaugh - $42
Riverdale Dunes, linksy, Pete and Perry Dye, et. al. - 45
Wellshire - a Denver municipal originally designed by Donald Ross back in 1926. Dream of finding out how much of his work is still there, and working on the restoration - $31
Fossil Trace - A really fun and interesting design by Jim Engh - $58.
Four very different courses, different experiences, $176. There are less expensive choices, also, but these are some of my favorites.
