@andy6026 unless the plastic is really really soft stuff I wouldn't worry too much about hot water and plastic. I routinely use a plastic bucket as my mash tun and the weakest part is where I attached a ball valve so I could hook up my manifold and it is still plenty sturdy and I've yet to get any off flavours. If anything the bucket I use might be a bit thinner than a homer bucket, though can't say as I've ever compared side to side since I don't own any (nothing against them, I just like white plastic so I can see colours easier and not have my beer tinted construction orange when looking into the bucket).
