There is a slightly used Hanno in the RCU Marketplace right now (or was) with an asking price of $250..

Most all my engines have been used and I've paid between $80-250 for them...The only NIB one I had was combo NIB Hanno/Aurora so I don't know how to calculate the price for just the engine..

The best guage of market value would be "the bay"...It appears to me to be a little spotty...I've seen some nice engines go for less than I figured...Then again I've seen others go for higher...I suppose it boils down to who want's it..

Just set your reserve on the least you would take for it and go from there...

I have enough already too or I'd be hitting you up myself...

Have Fun..

edit: The most recent NIB Hanno's I have in my "bay" history went for:
$359 (NIB not sure if it was MK I or II as it doesn't state in ad & can't see complete box)
$602 (NIB MK I engine, header & pipe combo from the dude in Korea)
$313 (NIB?? MK I engine and header)
