Mp3 Mixing Software? Options

[acidorro]

I've never mixed before and would like a program i can use to make professional dj quality mixes using mp3s.

I've been considering purchasing traktor dj studio 3 as it seems like a great program, and the demo is great, but if anyone knows of a good quality program that costs less which i could learn on i'd appreciate the info. also, live aspects aren't as important to me as i mainly want to use the software for making mixes at home.

thanks in advance for any advice,
