Product review (5 stars): Expensive, But Worth It
My wife and I just got this delivered on Sept. 22nd, which I believe is the first day it was available for sale as it's a new model.  She's always wanted a double oven, and we don't have the space for the typical wall model in our condo.  I must say it's quite the impressive sight.  It looks expensive - and it should because it is expensive for a non-luxury brand.  But you get what you pay for - the quality is there and you can see and feel the difference between this and your typical $1,400 range.  It comes with an iron grill/griddle that runs on the center 5th burner (the existing grate must first be removed).  The iron grates are much lighter than many stoves, so they are easy to remove for cleaning.  GE has an excellent reputation for its gas ranges as per Consumer Reports, and I expect this one to be no different.  The cooking performance has been excellent on both the stovetop and the oven so far.  We haven't tried the convection function yet though, so can't comment on that.

It has a tri-ring burner which is basically three burners in one.  It's kind of hard to explain, but really cool once you see it in person.  You have separate controls for both ovens on the keypad, which is really easy to operate with just a touch.  It can be locked for cleaning or to keep children from playing with it.  The upper oven is the smaller one.  It's good for pizzas, cookies, cakes, and other smaller food dishes.  It's probably the one most people will use most often.  The lower oven is the bigger one you'll use for roasts, turkeys and other bulkier foods.  The upper oven contains the broiler, while the lower oven has convection capability.  A few notes of caution about this model: 1) You give up the storage drawer most ranges have, so be prepared to store all your pans elsewhere; 2) If you have problems bending down or picking up heavy food trays from down low, this model is not for you.  The lower oven is basically on the floor and can be hard to access; 3) This model is slightly deeper than many ovens - be sure to measure before buying to ensure nearby cabinet doors and drawers will still open without hitting it; 4) Lastly, understand that this is a slide-in model, which means the sides aren't finished and you'll have a gap between the back of the range and the wall if your space isn't made for this type of range.

All said, this was a fantastic purchase, and we're very happy with it so far.  At the time of this writing, according to GE this range is a one of a kind - it is currently the only double oven slide-in gas range made.  There is a stand-alone version in gas/electric (finished sides and backsplash) and an electric slide-in version of this model for those who prefer those types of ranges.  People who desire Wolf, Viking, Dacor, etc. need not apply, as this is not a wanna-be pro range meant to compete with those, as they start at $1-2K more.  But it compares favorably with GE's higher-end Cafe and Monogram lines.  If you're shopping for the top of the line of a mid-tier brand and you can afford one, I highly recommend this model.

*UPDATE* - after living with this range for nearly 18 months now, I can update people on the reliability of this range.  It has been rock solid without a single problem.  However, it scratches unusually easily.  We have a few ugly scratches front and center despite being very careful with it.  So beware of that issue.  Also, the black metal caps on the burners permanently stain if just about anything but water spills on them. So watch for that as well.  Other than those two things, we have not a single complaint.
