Cramer: Guitar Center was decent, but its online sales were weak. Expectations for online shopping have been very high, so many were surprised that Guitar Center couldn't do better. What's up with Broadcom (BRCM)? -- Michael from New York James J. Cramer: Unfortunately, Broadcom is still suffering from a recent downgrade from Merrill Lynch. However, I believe Broadcom is a buy here, because its chips sell into a lot of growth markets, like wireless networking gear and next-generation cable systems. Want more Cramer?
