Return Pump Advice...

[a&m aggie 04']

Haven't been around here much lately but am about to get a little more involved with my tank. I'm upgrading to a 90 gallon and need some pump help. What external pump do you recommend. I've read reviews, but figured advice is best coming from a better source than someone selling the product.
So, give me your ideas on which external pump I should go with...Preferably in the $250 and less price range.

OK,
well you might what to do 10 times an hour. That mean take your 90 and times it by 10 so it would be 900GPH.. That will be good for your tank...

I understand flow rate. What I'm looking for is opinions on what return pump ppl are using. I'm going to compliment it with a couple Hydor 4's in the display for water movement.
Has anyone used the Poseidon Titanium?
