I very happy with this one I got on ebay for $10:
New Metal Tele 49mm Screw-in Lens Hood + Cap | eBay
Hood is good quality, thick metal. I use it with my M50/1.4 on K5 and it fits perfect, no vignetting. For shooting film it's probably too long, but there's a shorter one called Standard which would probably fit.
There's a version without cap too, but I find the cap very handy since I can leave the hood on all the time and put the cap on that.
My experience with seller was very good, not ultra fast shipping but certainly fast enough considering the low shipping cost.
