Geez, if you do nothing else, GO GET the rotisserie !!!!!
Then figure out which Weber it will go onto.......
The CharBroil may be OK, but I know of no one that has one to then get a review about performance & service.....not quite sure what it means with the infrared, it's charcoal & you can get a Vortex cone to do extra high heat on any of these machines.....
A Weber, on the other hand, if even used & under 10 years old, may be able to get parts under partial or full warranty ( I don't want to speak out of turn on this, but I've seen amazing customer service stories time & again from them)
The Mastertouch grate is extra heavy duty, has the removeable center you can set their wok or a larger one into, also other pieces are available to fit the center section.....it has a lid bale, so that's about like the hinge lid on the others, it's taller than normal as of this year, which is a plus for a lot of folks....
The iron grates on the Stok may be nice, but there's other ones that will fit Weber & the others also (Craycort, Chargrill center 18" removeable, etc.)
The ash pan system on Stok & CharBroil will drive you buggy, I can almost guarantee it (sorry, I've used Stok & a different C.Broil briefly at other people's homes & they aren't that good)
Now for used.....you can find Webers all over the place on CL & garage sales & estate sales......some ares of the country are easier to find them for a decent deal, but they are out there.....
They can be, in most cases, cleaned & rehabbed to almost like new.....if you go that route, we can send you to step-by-step easy guides to do that......
One final thing, I'm biased......all the Kettles below were free......flip grates were the only expense.....
