check if there is any ASIC ready to ship, I can't advise as I don't follow that market
To Mine LTC (scrypt):
With $10k you can probably get 4 miners with 4 good gpus (16 in total)
You can plug hash power into the calculator and it tells you how long it take at the current difficulty to ROI and how many you can mine per day
..but are you sure you prefer buy hardware rather than buy BTC directly?
It's a lot of work and it might be challenging if you don't have much experience with hardware and stuff
He said it the best. Mining bit coins just isn't worth it. I would not advise buying the ASIC miners. With the difficulty increasing quickly, the ROI on the ASIC miners isn't worth it.
If you have a lot of time during the day, I would just day trade BTC or LTC.
With that said, for fun.. I am mining LTC. Since I have the hardware already, it covers my electricity cost and I turn off the miners when I want to play some vids (XFX R9 290), but my 5870 is constantly running hashing at about 450 kH/s
