A really good knockoff i found

 I looked up galaxy explorer on Amazon and stumbled onto this set

I was surprised at the quality of the bricks.  The 2x1 brick feels slightly lighter than a lego but the clutch power and fit is really good.  This wouldbe great to make a classic space model.  Even the rod elements were straight without warping.  The translucent yellow pieces are handy too.
