Lugerdoc sometimes has M1900 mainsprings in stock, drop him a line. They also show up regularly for US customers on Ebay, the seller "dealoftheday$" seems to have a few on hand and lists them from time to time.
These springs are getting hard to find, and can be expensive - I have seen them range from $60 (Ebay) all the way up to $300 for NOS on some dealer's websites. It seems like $150 is becoming the norm - when you can find one.
I wish someone would make some reasonably priced quality repro's, as I have found that these springs are prone to breakage. I think this was even so originally, as DWM soon replaced them with more reliable coil springs in the 1906 model.
