The Biala Rebbe, Rav Betzalel Rabinowitz Shlita [there is another Biala Rebbe who comes to the States a lot. That is his nephew], has written SEVENTY sefarim, many of them based on his shiurim on gemara bi-iyun [his talmidim actually recorded them on paper]. Many others are on chasidus. WOOOWWW!!!
His sefarim are clear, orderly, and very worth one's time. They are called Mevaser Tov. Here is one. Many others are available for free download and those with the Otzar Hachochma can get just about all of them.
