That's what's been happening with me... The fact Dell prices can have a
fair bit of downward movement when you get the account manager on the
phone makes them especially attractive to the people controlling the
purse strings.

The biggest reason for me however is the lack of comparative reviews. I
struggled to get the LSI card to replace the PERC3 because all I had to
go on was qualitative mailing list/forum posts from strangers. The only
way I got it was to make the argument that other than trying the LSI,
we'd have no choice other than replacing the server+shelf+disks.

I want to see just how much better a high-end Areca/Adaptec controller
is, but I just don't think I can get approval for a £1000 card "because
some guy on the internet said the PERC sucks". Would that same person
say it sucked if it came in Areca packaging? Am I listening to the
advice of a professional, or a fanboy?
