2001 F150 Sirius Options??

[Geoboy]

Hi everyone.
I have decided to go with Sirius and need opinions/options for install.
I was looking at an expensive Alpine double din head unit and gave my head a shake. I had the 'ol "well I'll need a new head unit......but then new speakers to get the most of the head unit.....might as well add an amp if I'm gonna do that" routine.
Next thing you know it I am +$2000.00.
I decided not pump that much money into a 6 year old truck....especially one my wife drives most of the time.

Requirements:
-relatively clean install ie. no mess of wires and power adaptors
-don't need mp3 capability on the unit....just the radio
-decent audio preferably not modulated
-don't need portability outside of the car unless someone can convince me otherwise.
-budget roughly $300+

Where would you steer me to hardware wise.
I am willing to replace the head unit and don't mind an aux input for an mp3 player.....I just don't need it on the Sirius unit.
TIA

Sony has a line of inexpensive head units that have an AUX in on the front - I have the low end model that also plays MP3s from CDs - sounds a little better than my stock (2003 F150) - I do need new speakers though.
