The biggest enemy of any semi auto is the nut on the back of the stock. I haven't seen much difference in the reliability of properly maintained 1100s versus 11-87s in almost 25 years. Proper maintenance isn't hard or time consuming, but it is needed. A new 11-87 will be more prone to having issues with light loads than a standard 1100, but even that isn't hard to address if you know what you're doing.
I'm surprised no one has mentioned the Wal Mart Beretta. I thought that was the almost universal answer for someone looking for a semi and not wanting to spend a mortgage payment. I prefer the Remingtons to the Berettas, but there is not a thing wrong with them. I don't do plastic or flat black of any ilk.
