I used to use spray starch, until I had problems getting it here in Ontario.
One thing I noticed was that it would flake off, leaving white.
Also, that lighter fabrics would get scorched ... enough that I was scared to use lights.
Switched to Best Press ... and honestly it is The best ... IMHO!
Yes I was hesitant about the price, but once I was using it, price did not become an issue.
Like you ... if it is a good product, I don't mind paying the extra price.
Have never had any scorching or flaking issues.
One time with a push by an LQS (who did not sell Best Press), I tried her Flatter.
(or was it called Flatten?).
Her claim was that it was better than Best Press.
Well, IMHO it was not ... and Best Press was Still Best!
No doubt about it ... Best Press is my only way to go now!
