With help from the Coffee Geek community, I decided to buy a Hot Top roaster to upgrade (from hot air popcorn popper) my roasting.  I bought it from Sweet Maria's and it arrived in 3 days with 5 lbs. of Sumatra Onan green beans.  Thank you Sweet Maria's for great service as always.  
    I spent the first day reading the owner's manual and Sweet Maria's tip sheet.  It sounded a little intimidating, but when I finally started roasting, everything went fine.  I used the "auto" program for the first roast and used the recommended 250g of beans.  While this is automatic, you always have the option to stop the roast at any time by pressing "eject."  The cool thing is that you can watch the beans through the window and decide when to stop the roast.  For the first time in many years of roasting, I was able to hear 1st crack (about 12 minutes into roasting) and 2nd crack (very soon after 1st).  Before I couldn't hear the cracks because of the noise of the popper and my hearing limitations.  For the first roast of the Sumatra beans, I stopped the roast soon after 2nd crack.  The beans then eject and swirl around in the cooling tray for several minutes.  Made drip coffee using the roasted beans on Sunday morning and the coffee was super.  I plan to experiement witha slightly longer roast next time.  Wonderful roaster!

I recently upgraded to the B2K from a Behmor and I too am very happy with it (though I'd be even happier if I could roast 400 gms).
The default eject temp is 428 which will give a pretty dark roast (Vienna, at least, I'd guess).
Sounds like you're off to a good start.

Many Hottop users pretty much override the auto program.
For soft beans like Sumatran, you may want to slow it down a little (especially in the "drying" phase (when the go from brightish green to tan). It seems to happen in the 260-320 degree part, I think.

Many Hottop users charge (drop the beans in) at around 250 degrees and higher.
A little before 1C, you also might try slowing things down. I find 1C usually happens around 370-375).
One rule of thumb is that 1C should be about 90 secs long and then 2C should happen about 90 secs after that (if you let it go that far).

You can play around with these parameters and see how it goes.
I find the Hottop to be extremely consistent such that if you use the same settings with the same coffee (same amt of course), you'll get almost identical roasts.

PS: I use the iPod/iPad app roastmaster to track everything and it's great (it's $10).
When I had a Behmor  I used the free PC app roasterthing.

Between here and homeroaster.org, you can get lots of info.

Thanks for the tips.  Didn't know there was an iPhone app, but it doesn't surprise me. I'll download the app. I'm very excited about the Hot Top and what it can do.  Happy roasting!

I'm not sure I'd actually want to use the app on an iPhone or iPod, but if you have an iPad (or even iPad mini) it should be quite useful.
