[Klipsch mix advice please]

OK,

If I do buy the SB 1 speakers, I will use them as the mains. Is this a better solution (for overall sound quality) than buying another set of quintets? Can you tell I am on a limited budget right now?

Thanks

I am a novice at home theater and have assembled the following equipment that I use for watching DVD's:

Onkyo TX DS494

Klipsch quintet front speakers

Klipsch SC.5 center

Sony SA-WM40 Sub

I want to add surround speakers and the options that I am considering are

a) buy two more quintets or,

buy two Klipsch SB 1 speakers and use them for the front. (I would then use the quintets as surrounds).

Which option would you recommend and would mixing the different Klipsch speakers sound OK?

Thank you for your help!
