Help me spend my money!

The main 'cheaper' systems that I've found are
FAST Anolog - from Summit, $160
AEM - Ebay, $160ish+
Innovate MTX-L - from Innovate, 200; Ebay, $160ish+
GlowShift - $185
AutoMeter- $185
14point7 - $160
PLX - $180

The AEM and Innovate are the most popular ones from what I can tell, with some using PLX. I just can't decide which one would be right for me.

67Dart273, could you read both banks or just one when you had your Innovate?
