I'm buying a backdrop and stand setup. AKA, Muslin holder.

Just looking for any advice on what to buy. Maybe there's a favored brand or standard for this type of thing?

It will be used for portraits and product photography.

This Julius Studio one seems entry level and slightly more favored on amazon https://www.amazon.com/dp/B072BCNRTY/ref=psdc_3444601_t1_B00E6GRHBO

I also need the muslin backdrops, in at least white and black. Would also like medium grey. I guess I could make use of green.

So maybe this package? https://www.amazon.com/Julius-Studio-Adjustable-Background-Backdrop/dp/B075SQG2HW/ref=pd_sbs_421_3?_encoding=UTF8&pd_rd_i=B075SQG2HW&pd_rd_r=F6YC1P4VZKX44WD280RP&pd_rd_w=0Lhev&pd_rd_wg=LZm7z&psc=1&refRID=F6YC1P4VZKX44WD280RP

Thanks
