Single time purchase from China

Hello All,
I am a blacksmith by trade and occasionally order items which are imported. The last time I did so was some special leather from Norway and I exceeded the $2,000 informal cutoff amount by abut $50 and go hit with a large broker fee (had to find a broker in Milwaukee, WI late in the day that I went to claim the item at the airport).I did not know of the formal/informal thing prior to ordering or I would have simply split the order.

At any rate

Now I am looking at a single machine (an induction furnace for heating metal) from a manufacturer in China. The unit looks good and the costs are, well, low and the company seems good judging from a few emails. The comparable unit in the US is about $20,000 while the Chinese made one is about $4,000. I struggled with the idea of buying Chinese, but it is a matter of getting this one or none at all. The unit weight is about 120 pounds plus crate and the size of a large microwave oven.

I have no problem with working with a broker, but would like a heads up on whom to contact.
Again,
I live in Wisconsin and would prefer to do some form of delivery with few hassles. I can drive a bit to pick this up, but not to California.
