Subject: how much does eval effect strength?

How much searchdepth is it worth giving up for a stronger evaluation function? I
often find, that while my program is playing GNUCHESS, or AnMon, both the other
computers give a reasonable + score in a position in which neither side is up a
pawn (and neither side will be in the ply 8 searches they are managing). My
almost entirly tactically based program gives a slightly worse score, and loses
20 moves later (the position being dead lost the whole way). But lets say, I
code a much better eval function, and as a result, lose about 1 ply. Is it worth
it? or does the extra ply really count heaps.
