Guys, after a lot of consideration of your great advice, suggestions, and experiences, I settled on a DS Machine 1500WH. It was delivered and installled today!!!
Here's a pic of my new baby after the install:
Probably won't fire it till next weekend--taking an extra day off, so I'll be around three days to get to know'er.
You can see from the pic what I was saying about the low thimble. The collector hood in the pic is tied into the return side of my heat pump air handler. 10 of the 12 warm air circulater tubes on the top of the stove are directly under the hood--should work out pretty well. Can't see it well in the pic but there's a MPD up near the thimble.
Can't say enough about the folks at Blain Supply and their installer, Pequea Renovations. They were in and out of here in less than 90 minutes. Did a chimney inspection too, and found no issues. They were very careful about getting the stove through our finished TV room and into the unfinished area of the basement.
Thanks again to all of you who weighed in on the discussion!!! I'm sure I'll be around asking plenty of questions when I get it started.
