The Yashicamat 124 and 124G are the best of the Yashica TLR's I like my 124 and I use it quite a bit when I'm in Turkey, it's lighter than my 2 Rolleiflex cameras and the results are excellent. I think weight with TLRs is important I used to have a Mamiya C system two bodies a C33 & and a C3 with a couple of lenses fine if that's all your using but heavy compared the a Yashica or Rolleiflex, I'm often using a TLR alongside an LF camera.
In the UK my main TLR is a Rolleifllex E3 f3.5 Xenotar which is in mint condition so I'm tending to use my Automat with it's Opton Tessar more. I picked the Automat up cheap at a flea market and it's more of a user camera.
Another flea market find is an MPP Microcord MkII, essentially a British made Rolleicord with an excellent Ross Xpres lens. These are excellent cameras, usually quite inexpensive,and the lens is better than a Tesar/Xenar and also the Yashinon in my experience.
