Regardless of what type of screws the Nextar has, keep a set of standard and metric tools (Eventually, you'll need both).

Good stuff to have:

Metric and standard Allen Wrenches (Preferrably ball end)
Glow Plug Wrench
Needle nose pliers
Small cresent wrenches
8 or 10 inch Adjustable Cresent wrench
Long, slim Screwdrivers (Straight and Philips)
