I've got about 700 data points.  They're arranged irregularly
along arcs arranged in sort of truncated fan-shape.

Not recently.  I spent a month or so wrestling with bisplrep a
while back, but was unable to get stable results (either with
real world data or with the example from the tutorial):

I switched to a trianguation scheme shortly after that posting,
and haven't tired bisplrep since then.
