I don't know where you live but a guy in Minneapolis has a slightly used Capital Culinarian on Craigslist for $2250. He mentions the rotisserie in the description, but I don't see any lights next to the oven knob, so I think it's a manul clean without the rotisserie. Still a great deal though.

unless you go used then for under $2800 you are probably looking at a Bertazzoni (around $2400ish I think) or an NXR ($1999 or less)
If you live in Canada and have a Costco card I believe you can get Blue Star for under your price range.

Personally I would go for the NXR and as for your Griddle instead of the probably sorta small cast iron Id get a Steel griddle which are way larger and once seasoned totally nonstick just like cast iron.

here is the difference between the usual Lodge Cast Iron which is actually made for a Coleman 2 Burner camp stove Vs a nice Steel Griddle made for a Gas Stove.

Oh and that is one of the best things I like about the NXR and really most all of the pro style stoves is they do not have any Electrical Panels to get messed up with steam/heat/water or whatever.
Pretty ignorant idea really to put those dang electronic panels on a stove where you are boiling water right next to it, really makes no sense.

You can get the Bluestar RCS 30" in the US for less than $2800. Abt has them for about $2800, and I was quoted $2550 from my local dealer.
