I used the 50mm 1.8 and found it great but it felt very cheap and plastic.
What other 50mm options are there and what prices are they?
If what you want is a better lens around 50mm, not necesarily with a mega wide aperture, then Canon EF-S 60mm f/2.8 Macro is a fantastic little lens.
I second HoppyUK! I sold my 50mm 1.8 when I got the 60mm Macro and can't say that I miss it
