Is the 28" Omnivore worth it over the older 28" Blackstone?

Yes for most buyers. The Omnivore plate heats faster and more evenly, and the rear grease system is easier to clean. The older model is still fine if you find it and want to spend less.

How many people can it cook for?

524 square inches handles burgers, eggs and pancakes for four to six people at once. For bigger crowds or two full meals side by side, the 36" four-burner model gives more room.

Does it come with a propane tank?

No. It runs on a standard propane tank, which you supply along with the hose and regulator. The hard cover is included.

How hard is it to move?

It weighs about 84 lb and rolls on two caster wheels, so it moves on a flat patio but is awkward over steps or grass. Plan a spot and leave it there.

How do I keep the griddle plate from rusting?

Season it with oil before first use, scrape and oil it after each cook, and keep the hard cover on. Dry it fully after cleaning, since cast iron rusts when left wet.

Can I use it for anything besides burgers?

Yes. The flat plate works for breakfasts, stir-fry, fajitas, fried rice and searing. There is no side burner, so boiling or sauce work needs another stove.
