I searched for months for one in the US and never found one for sale aside from Lui Kang's wares... The market on the Gladius has never been soft. The market on the satin models has been even less soft. Murman has probably bought and sold most of the ones I've seen for sale recently, and that's only a couple of them. The one's Busse has listed recently were gone as soon as they were made available and they were also priced very high. These are expensive and typically a grail item and seldom pop up for sale. In the past 2 years, I think I've seen 5-6 privately sold, and I believe 2 of them were the same one that went twice.
I've seen the Combat Grade go for 1000-1400, with most being at 1300-1400.
That customized/stripped combat grade is priced at 1700.
All of the CS Satin Blades I've seen go for like 2k-3.2k.
The market was softer back in like OCT/NOV when ppl were burning through cash and saving for the Holidays. Prices typically creep back up during tax season as refunds pour back in and people have more disposable income.
If you are after a "deal", I would seriously go the DIY route and pick up a coated one, and wait until you find one for 1000-1200 and spend some time with it making it look the way you want it to look.
