I am getting the Cannondale frame

So, one purchase creates the need for another, I need a stem (getting a ritchey adjustable one), and another, I also need an oversize handlebar...

Saw one in Carbon by a Performance house brand (E3), looked good but @ $150, its too much.
The salesperson told me I could get "much much" cheaper ones in Alu (fine by me) but couldn't tell me where and which brands....

Cheaper alu oversized alu handlebars...Is this true?
