What size room is your system in? I bought the Velo VX-10 a few years back and while I do enjoy it's performance I now am wanting something bigger and better (perhaps that will never change).
I second the suggestion of saving up a bit more and getting something you will really like.
I for one am currently saving up for a DIY sub kit from Rythmik audio
And about your center channel, find a good deal on ebay for the Polk CSR center or save up a bit more for that as well. Buying a center from the same product line as your fronts would be ideal.
