Yes do buy, and get a hood too.
Filter = $10 for a basic UV
Hood = $7 some ebay shops.
After buying my 50mm F1.8, I took it out to use, lent it to one of my girl-friends and the filter ended up with quite a few scratches. Partly could be my fault too due to scratches made by my lens cap. Double Coated filter some more =(.
I can't imagine what I'd have felt if my brand new lens had scratches on that day. In anycase, the front element is slightly deep-seated in the lens as well, although this helps prevent scratches, it promotes collection of dust on the grooves, another reason why you might want a filter.
Buy from where? The usual reputable shops, and make sure you know the prices... $10 for a normal UV filter should be fine... can get Hoya too for $10 actually.
thanks for your reply! anw, is there a difference between the UV filter and a Hoya?
i don't think you should get a filter or the 50 1.8.
because the lens is set so deep in, there will be a large gap inbetween the front element and the filter. as such, you'll get flares and ghostings quite often.
i learned this when i shot a few family shots at home. direct light sources caused many flares in my shots, and in this case, hoods wouldn't have helped.
secondly, because the front element is set so deep in, i think it's really quite difficult for you to scratch it.
lastly, the lens is cheap. if this were a L, i'd advise you to get a filter on from day one. but because the 50 1.8 is so economical a lens, i don't see why you should be THAT worried. anyway, cost is besides the point here. it's the flares and ghostings that make me say no no to your 50 with a filter.

I wouldn't bother with a filter for the 50 1.8 as well.

Anyway, about the IQ degrade, seriously, does it matter that much?
I haven't had flaring issues, even without a hood.
If you can borrow a cheap filter from somebody (EF 50 1.8 has 52mm thread) then go out and shot with lights directly in the frame (sunlight, street lamps etc.)
i think it's better to be safe than sorry.the filter can also be taken out with ease if you're facing direct sunlight. anyway, he alrdy bought it last month. paying 10 bucks for a filter wouldn't hurt to keep the lens in it's best condition.
Just my 2 cents thou

If you can borrow a cheap filter from somebody (EF 50 1.8 has 52mm thread) then go out and shot with lights directly in the frame (sunlight, street lamps etc.) with filter on and off. Very impressive and doesn't need much explanations.

Ok, some personal experience. I used to have a Hoya Pro series UV filter on my Tamron 17-50. Got a few splashes of water on it and also accidentally touched it with fingers. Cleaning was hell. I don't know what coating Hoya uses but it's a nightmare to clean it properly. After removing the filter I had the same with 'naked lens': droplets and dust. Cleaning was a piece of cake. The front element coating is really well done and if you read other articles about it then the issue of scratching the coating while cleaning seems to be gone. Now I use the hood (comes with the lens anyway) and the filter is only there for really touch conditions.
In addition I have tried B+W filters (uses the same glass as mentioned in the article) and it's great. But it comes with a price tag. If you want to increase the value of the 50mm f/1.8 lens by 50% just by adding a filter then go for B+W. Otherwise just be careful and use the hood.
