Where to buy power transistor in small qty?

I need to replace the left channel mosfit power transistor of my Creek 5350. The manufacturer is Harris semiconductor and the part# is RFP30N06LE. I did a search and the only site I found that sells Harris brand is Gerber Electronics and the minimum qty. that you can buy is 805. I only need 4. Does anybody knows where to buy this in small qty? It needs to be Harris brand to match the right channel.
