It's surprising how actually holding a camera in your hands shatters your perceptions of it from what you read in the online forums. After a bad experience with a used Rolleiflex, I decided to go for a Mamiya TLR system, being less expensive in the long run and easier to get repaired in my area. I received today a C330 with the 105mm f3.5 DS lens, and because I intend this to be my main MF camera, it will probably replace the Yashica D I've been using so far. In the meantime, I took pictures of both side by side. The Yashica is lighter than a Rolleiflex, and a tad smaller. It's an excellent TLR, but the lens quality has its limits! The Mamiya C3xx series has the reputation of being a "boat anchor." Well, it sure is heavier, but to be honest, it's not the monster that some comments make it to be. It's not a Gowlandflex 4x5 TLR! So I hope these little snaps will give you an idea; the Mamiya is marginally bigger than the Rolleiflex/Yashica TLR, although it is heavier. But it's not a brute like a RZ, nor is so heavy that handholding it is unwieldy. It's perfectly capable as a handheld camera.
