I got my at a Russian ebay, for about ... less then 180 dollars.
my short evolution looks like this:
17-55 (kit lens) > Canon 50mm 1.8 > Canon 50mm 1.4 > Sigma 50mm 1.4
ofc, now I diluted it with some tele, macro and wide angled ones.
wish you good luck, it is the fun process of collecting your arsenal / tools of the trade, need no rush all the way along!
