Going To Purchase First Low Cost Miner Need Your Thoughts

[kflo01]

Ive been mining for awhile with my CPU and GPU getting a few coins here and there on my gaming desktop when I am not streaming media or playing on Steam. I want to dip my toe into the pool so to speak with some low cost mining hardware. I was hoping to mine some alt coins. I was looking at these 3. Which do you think would be the better choice for now and/or the future. I was purchasing mining contracts but that was getting costly.
I cant afford anything over say $200.00. Electric bill isnt really a factor I could have free electric if need be. I am  just wondering from a horsepower stand point which would be best. Im looking at:

1) Futurebit Moonlander 2

2) GekkoScience 2PAC Rev2

3) Btimain Antminer U1

4) Gridseed Orb 5 Chip

Thanks in advance guys

The only one that might be worth getting is the  Futurebit Moonlander 2.

Lostpike. Thanks for that post. Will look at the videos now.
Just a quick look at them and the futurebit seemed like the best buy but I will dive into the videos now. Thanks again.
