If there a low impact way of searching a colomn for a change.

i.e. Column 5 has 204 rows of "Text1", then 318 rows of "Text3" then 128
rows of "Text2", then 356 rows of "Text3", etc. At run time, I "know" column
5 and how many total rows I have, but I don't know the actual values I may
find or how many of each I'll have.

Fuctionally, I would like something similar to:

Set rngSearchRange = Range(Cells(1,5),Cells(lngLastRow, 5)
strSearchText = rngSearchRange.Cells(1).Value

Set rngHitCell = rngSearchRange .Find(What:= ^strSearchText)
'First cell that
doesn't match

While Not rngHitCell is Nothing
<Do processing on Section upto HitCell

Set rngSearchRange = Range(rngHitCell,Cells(lngLastRow,5)
strSearchText = rngHitCell.Value
Set rngHitCell = rngSearchRange .Find(What:= ^strSearchText)
Wend

Right now, the fastest way seems to be read the column into a variant to
move it into memory, iterate through the array, and process worksheet based
on index values in the variant. This question is not a matter of finding a
way to do what I want, it's about finding a better way.
