Mining Question

I used to mine back in the day when it might have been actually profitable. I used a USB miner and it drew so much power it fried my motherboard. I decided to get a powered USB hub and a Pi to manage the miner but instead I gave the miner to a friend. Logging back in today the 5 cents I mined is now $50.

I'm considering getting solar panels as my power bills are high, not because of any mining but they just are. I am going to put the miners under the hot water tank and specify to the solar power people I want a light to turn on when the solar power exceeds the power coming in off the national grid and only mine when electricity is basically free.

What miner should I go for? I'll be spending under $1000 to start until it brings something in and I'm not restricted to Bitcoin, I'll mine others if it brings in money. I used to mine Bitcoin on slushy's pool. I'm an idiot for stopping.
