So, I was tempted to start some mining a few weeks ago. My son and I built a used rig and found some local sellers for some inexpensive video cards, aka GPU's. For under about $250.00 USD with 2 GPUs, we fired up the rig, and it's been running smooth. Nothing big, but it's interesting to see the possible returns. Obviously the fluctuating price of the coin will dictate ROI, but as of today's price we are bringing in just under 1% a day.
I was considering the L3+ from Bitmain. Are you mining SHA-256? LTC looks pretty profitable to mine right now..
Mining Ether to start, then we may expand from there into other coins. Just testing the water.
You can still buy a lot of graphics cards. Just have to know where:

Yes you can buy GPU's, but not the ones we need for ether, unless you want to pay above msrp.
