What you want as miners from a miner. For example Size, power hookup, Easy to use, lots of fuctionality? You tell us.
Well, my humble opinion - take somewhere AntMiner S2 by Bitmaintech, disassemble it and explore it, and make something your own in the same form-factor and with better specifications (keep in mind that they promised to provide some easy and unexpensive way to upgrade S2s to 1.8 or 2 Th/s) for the same (or better for less) price. Standalone, web-GUI, 0.7 or less W/Gh, a possibility to overclock - it is a minimum of what we need from miner. We also need well-known supplier with wide dealer network, who make his devices in good faith and provide reasonable warranty time...I do think so.
