The best thing you can do when going thrift store hunting is have a key puller on your keyring. Dont pass up dome with slider boards with alps compatible keycaps if theyre cheap, alps caps can be kindof a ***** to source. Since you already have a v60, the matias based v60 (new alps clones that use real alps designs) is a good starting place. Matias click switches are pretty nice, but if you find a nice original alps board, you can swap the switches into the v60, since matias and alps use the same mounting system and pin configuration. welcome to the wonderful world of alps!
