For example I purchased my first Antminer S1 through Sushi's group buy in early February for 1.45BTC

I set it up and overclocked it to 200 GH/s and started mining on February 12th.

Using http://retrocalc.net/ I see I've roughly made 0.8 off that 1 Antminer S1(2.24 Total BTC mined).

I don't think making nearly $500 off of one miner(out of several I bought) is just barely making ROI, do you? Another factor is I luckily have free electricity, so helps a great deal.

Now I've sold most of my Ants, but I've held onto Antminer #1, as that little guy is proof that you can ROI in this difficult environment. He'll always have a place in my BTC heart.... Cry

I don't know if those numbers are correct, it's saying 200ghash would make .05 bitcoins a day in mid-february. doesn't seem correct to me.

but sure doesn't hold a candle to buying a radeon 5830 for $100 from newegg in 2011 and paying it off in like 2 1/2 days

Yea, I'm late to the game(started late 2013) but I can assure you I was making around 0.04-0.05 Bitcoins in mid-February since difficulty was at 2.6 Billion

I wish I had mined in the GPU era, but oh well that boat has sailed.

You can be sure that the retrocalculator is pretty spot on as it pulls it's database from http://blockexplorer.com/q/nethash

Even with 1% variance due to pool luck or any outages, you can see I've made out with that single Ant.

Much much harder nowadays obviously with each difficulty increase, but not impossible as most would have you believe. You have to pounce on the right hardware at the right price point. If you aren't close to mining ROI, best to sell it right away for BTC to recoup losses and turn the sale into net profit. Also, it doesn't hurt to have cheap or free electric!
