If the BK2000 was secondhand or discontinued that may explain the price. But the iron looks like a Weller design from the heater and tips, and all indications are that the station is 90W according to Bakon, which could be overstated.
The BK2000A (90W) I found on gearbest was $156 and ebay was $200 and considering it comes with all the idiosyncrasies of a Chinese home brand station (questionable specs, safety, reliability, warranty) combined with the older style iron, not great value at all.
