From what I have seen, most of the model under $300 are not really worth buying,
they are too flimsy. Basically you are looking for power, the grids, and the framework.
The side burners are optional. Good solid stainless Steel are expensive, but they are
easier to clean and maintain.
A commercial BBQ would cost $2,000 which included many safety devices and allow you
to use natural gas.
I would prefer a good Weber that you can use real charcoal and less expensive.

I recommend a Weber, which start from under $100.
You maybe driving a Prosche, while I drive a 2003 Toyota Van.
I consider reliablility and  performance when I invest on tools,
just like you and me will not buy a calligraphy brush for $100.
I buy quality that last, not flashy products or toys. It is about value.

Get a powerful electric contact grill instead, it is inexpensive, versatile,
good for indoor/outdoor, and easy to clean. Well under $200

A good electric panini grill would heat to 300C/675F, more than adequate for home cook.
and it cook from both top and bottom elements. not Foreman Grill.
On the other hand, Weber lasts almost  forever so take your pick
If for steak alone, I use La Creuset Grill iron on Propane stove (22,000 BTU),
very nice grill mark for presentation.
