I think $99 would be the sweet spot for pricing, personally. It's low enough that people like me will buy it no questions asked, and it will allow people to easily upgrade to that as opposed to the ECB. I could see an MSRP or $129, but they usually be on sale for $99 as well.
Oh yes, and I would be beside myself happy with a 26.75" WSM. I'm sure it would take a lot of fuel, though.
