I am thinking of getting a reflector kit but am not sure which to get. Seems like they are all relatively the same size (40-44 inch). Some are round, some square. Some better than others? Should I get the stand that holds them or just the reflector? Also, I am considering a "Professional Filter Kit" by Clearmax, specific for my camera lens, which includes 4 close up lenses. I can't find any information on this company. Amazon customers have 2 reviews: 1 "5 star" and 1 "1 star". The sales guy at Ritz Camera talked me out of extension tubes and promoted the close up filters. I left with neither! Any opinions are appreciated!
