Exactly as it states above. I want to mine other currencies, not BTC. Paying 13k for a miner that you will probably never break even with doesn't make much sense to me.

If I said money was no issue, what would you recommend? I plan on purchasing the best hardware to retain the most profits.

I followed this page: https://litecoin.info/Mining_hardware_comparison, and it shows this to be the best graphics card for mining: 7990, HD7990-6GD5

Is this the best at the moment on the market? If so, can I use this to mine coins such as Dogecoin?
