No such thing as a "good deal" today on on bunch of Mantles especially with your requirements.... Now a few years ago I got some "good deals" (by today's standard) but even then most people didn't realize prices were reasonable. But that was then, this is now. Today's market is still very hot for mantles. It's like you are asking for "reasonable prices" on Mantle's now is like asking for good prices on Tom Brady....about a month ago....(before they lost the SB). An example of one of my good deals (about 5 years ago...)
