I am a big fan of Shenpo. Have a couple of their sets (square box/trays). Never had one that showed up wrong in any way.

They all have all the keycaps and no extras (sometimes you get repeats), impeccable dye-sub jobs, straight spacebars and thick walls. Great overall quality and QC and at a low price.

Only downside I can think of really is, well they only make beige sets.
