I'm looking for a high-end 220V->110V step-down transformer (for US equipment) that is properly engineered and provides quality power output inside the ~3000W envelope. Most of the transformers found in consumer electronics stores are poorly made and sometimes outright dangerous (I'm an electrical engineer by training).
I am thinking something along the lines of a data-center quality step-down unit, maybe something like this except with 220-240V input:

The only semi-reputable product I've found is made by APC (Schneider):

Do folks have any recommendations? I'd prefer to spend under $2000, but if it takes more than that to get decent quality I can stretch.
I've done a search on the forum and haven't found any threads focused on high-end transformers.
