Both the wife and I dive and snorkel, we use Oceanic Vortex V16 fins (theyre not called flippers) but we both use different masks, i have an Apeks mask with Cressi snorkel , she has a Typhoon snorkel/mask set.

If you have a dive shop local to you your best bet would be to pop in and try the masks on, the brand is pretty much irrelevant really, it's all down to how it fits your face.

A decent snorkel and mask set will start at about 50 quid with fins starting at about 30 quid, so it's all down to what you are prepared to spend.

PS where are you staying in Egypt?
