Hi hi 5, I was checking out for reflectors too. someone is selling here
Alternatively, at TK Photo, they have one that is pretty big, it's a 5in1, almost 4ft by 3ft open going for $90. Whereas CP has Photoflex's 5in1 for 200+. EG has one opened up diameter 80cm for $80, also 5in1 but smaller than TK Photo's.
