Help me choose an ECU

[vex]

Damnit TTT if you say buy a Motec I'm going to stab you in the eye and lick it like a lollipop. I'm a very poor newly wedded college student.

Okay, here's the deal. I'm interested in buying a stand alone ECU for my car. Here's what I currently have and what I want:

1. I have a T60-1 Ceramic Ball Bearing Turbo that is mounted to an S4 NA engine via a custom turbo manifold.
2. I will have a custom intake manifold
3. I have NA drive train
4. I will have a digital dash
5. I want to have EGT, wideband, and boost available on the digi dash
6. I want independent spark control (ie leading and trailing able to be set on the individual rotors if possible--not wasted spark)
7. I would like a high resolution map for fuel and spark
8. I plan on upgrading the engine at some point in the future to 20B or 26B (whether of my own make or Mazdacomp)
9. I would like to have at least 15 minute continual datalog (datalog the last 15 minutes of my driving)
10. would like to have auto fuel correction based on wideband readings
11. enough inputs/outputs to run the necessary accessories--Radiator fan, fuel pump, etc
12. allow custom map for alternate output, ie: rpm/load for a pulse width modulation/square wave voltage.

I'm considering one of the three following ecu's:
Sprint RE
Platinum Sport 1000
Platinum Sport 2000

Which one do I go for?
