If you do some searching, you can find them. It takes times as there are a lot of companies, most being just middlemen and not the actual manufacturer. I had the same idea as you and spent many hours of search and e-mails. Alibaba is the place to start.The best price I found on the particular blank I was looking for was .95 each and had to purchase 1,000 Not a bad price. yeah, not a bad price if I actually receive my merchandise or the of the high quality I thought I was going to receive. There are just too many companies and factories to know which one or ones are reputable. I just buy my blanks from the few vendors that order from China. Believe me when I tell you that they have stuck with some crap. Take a lok at some of the 1.5 and 2.5's that are out there. You have to fill in the seams and sand the bellies smooth. Those are the crappy ones. There are ones out there that require no prep work and run perfect. I buy in larger quanitites and get a better price. I don't mind paying a few pennies more and let the vendors deal with the headaches. Just look on e-bay and you will see a few people gettting rid of the ones they got stuck with. There are good quality blanks and there are, well...........crap. Of the good quality blanks that I have bought, I have yet to throw one away in the trash because it was made poorly.
I rather support the Chinese econony @ $2.00 a blank than the Japanese for $25
