I received this Stanley 64oz growler as a wedding gift last year. It's double-walled and stainless steel. I've never had any issues with the seal on it, and I really enjoy how easy it is to pour from thanks to the big handle and wide mouth. Looks like it's around $36 right now too so within your price range. There's also another version for $64 that includes 4 12oz steel tumblers.
