a good lug wrench can be had at Sears ... get the 1/2"
breaker bar (long bar with swivel socket-thingie at one end.
get the one that is about two feet long) and a 19mm short
socket and a short 3" extension. total price about $25, i
think. but you can get most any lug nut off.

another neato gizmo is a Vortex Bolt Spanner, part number
000-093-005B. for about $15-20 at some vw dealers parts
depts. comes with a reversible 19mm/17mm socket (the 17mm is
for mercedes). handle is extendible to about 2.5 feet long.
really easy to remove/tighten lug nuts. and stores easily
under the front seat (unless you're a camper).

hope it helps.
