Truely, Legend sucks:)

For me, it sucks the least when I construct my legends by hand.  This means 
that my legends tend to look like:-

ltxt = StringReplace[#, {".AMR" -> "", "203" -> "LF95"}] & /@
llin = Graphics[{pcol[[#]], Line[{{-1, 0}, {0, 0}}]}] & /@
lgnd = {Transpose[{llin, ltxt}],
      LegendLabel -> "Compiler",
      LegendOrientation -> Vertical,
      LegendShadow -> None,
      LegendSize -> {.2, .4},
      LegendPosition -> {.75, -.25}

and I use them via ShowLegend[graphic, lgnd].  Often, considerable
in the settings of LegendSize and LegendPosition is required to get the
positioned correctly.  This seems to be sufficiently versatile and allows
me, for 
example, to have a single Legend for a GraphicsArray of Plots.  This method
finer control over FontSize and Line thickness.  Because the graphic postion
of the 
Legend is constructed by hand, it allows PlotSymbols and Lines to be
overlayed and
coloured when (if?) you want to have GraphicArrays and/or Plots with symbols
on them 
so that you don't pay a premium for publication of Figures in colour.

The problem is that coordinates in Legend are based on the single graphic
rather than
on the plot within the graphic. 

For Contour & Density plots, Wickham-Jones' ExtendGraphics package has some
options and it may be worth trying these.
