1350 for the newer romulator.... 
i'm waiting for someone to come out with an auto-tuning ecu using a wideband o2 sensor. i think someone is actually working one over in the mr2 spyder forums.

Megasquirt and Megasquirt II have auto tuning software using a WB (or even a narrow band only for low speed areas of the map).
My whole setup has totalled about $500.

Here's a section of the megasquirt tuning manual:
You can also use auto-tune to help tune your VE table.
Auto-tune is an algorithm built into recent releases of MegaTune that automatically tunes your VE table based on EGO feedback. It is similar to MSTweak3000, but operates in real-time, without a datalog, and on any variant of code and processor, including MegaSquiirt-II, that uses MegaTune.
With a narrow band sensor, you can use auto-tune with any algorithm and any sensor to tune the low-power part of the table, it will get you to stoich (or AFR targets) quite nicely, which will give you a starting point from which to extrapolate the high-power part.
You don't need a dynomometer to get the high output regions of the VE table done, but you definitely should NOT use auto-tune with a narrow band sensor for that part of the table, you'll end up with broken or melted pistons. In order to use auto-tune for WOT tuning, you must be running a wide band lambda system (sensor and controller), with appropriate AFR targets in the AFR table. If one of these requirements is missing, then you must rely on seat-of-the-pants and experience.

yeah, i've been through joplin a few times before. seems like a pretty nice place. are they any local meets around there? i've been to branson z fest before and will likely go again but that's the only one in missouri i've been to.
i read a thread over on hybridz and someone was saying that the megasquirt basically doesn't support cop ignition. you guys know if this is true?
if so, i might have to change around what i'm going to do with the vh45 and use the romulator or change the ignition around.
