Classic Accessories brand covers seem to get good reviews although I haven't had one. I bought one of the new Weber covers (7130 I think) for my last generation E330 and it blew out a seam in less than a year. Weber did warranty it but it's pretty lightweight for the money. The older Weber cover I bought in 2015 is still fine, I think the number is 7107 and it looks like Amazon has it still, and quite a bit cheaper than the new cover.
