I ordered that hood to replace the Broan Elite e60000 that we had previously. I like the variable speed control. We are keeping the stainless backsplash from the prior unit as well. I initially planned to do cabinets over the E64000, but now my cabinetmaker is making a hood cover for it instead. It still worked out to be the best hood for the buck with 600 CFMs, baffles and a decent depth. It will hopefully be installed next week.
I ordered it from AJ Madison as well and had a good experience with them other than the knucklehead delivery guys that smashed my mailbox....

It is on my short list. I have a Zephyr Power Tempest on my list but it is almost 1,000 compared to the Broan E6400. I also have an XOT30 on my list that is closer to the Broan in price than the Zephyr. The Broan hood offers a lot of bang for the buck and I emailed my appliance guy this morning suggesting the Broan. I am hoping to hear back from him soon!

I am trying to decide about the stainless backsplash. How hard is that
to keep clean? I am wondering about stainless vs tile.

When we moved in the kitchen had the stainless backsplash with shelves. It was the ONLY thing I liked about the kitchen before! It has been super easy to care for. There are a few small scratches from who knows what, but a little Bar Keeper's Friend while it was down in the garage and it looks almost new again. I don't know that I would pay $400+ for it, but I am happy have it. I read that some have had local sheet metal fabricators make one for much less. The shelves are my favorite part. I didn't use them for food warming, but for utensil storage, etc.
When we changed to a wood hood instead of leaving the stainless hood, I considered not using the SS back splash for all of two seconds.

I have that hood in 30". It's attached to an 1100 CFM inline blower. It provides excellent ventilation, and I like the baffle system better than mesh. They are easier to clean by hand, and you can also put them in the dishwasher. ALthough there is variable speed, I find that I pretty much always use the max hi speed. I do have a few complaints. The knobs are small and kind of hidden. Hard to find them. I would have preferred a setup like the GE monogram hoods, where the knobs are outside. Also, the knobs themselves are very cheap plastic and keep loosening. I ended up buying new knobs from Home Depot that fit much better and are much tighter. They only cost a few dollars, but it just annoyed me to have to fix something like that on my own. All in All, I like the Broan.
