Ok, I missed the Bitcoin mining train. 
Nothing is missed, ASICs are future of mining. Now everyone have invested into one of companies and are waiting for result. You can join them. Currently existing ASIC models are Avalon's first batch and ASICMiner's private stuff + some of USB miners they have sold. That's all. Everything else is either not yet delivered, or not yet developed. ASICs like Bitfury, ButterflyLabs, KNCminer are promised to be developed soon. Read about them here on forum and invest if feel so. IF they will deliver product in promised time - you will get money back, plus a lot on top. But always keep in mind that they all can be just a scam.
and those better investments are ??
ASICMiner shares. Go to bitfunder.com and invest in G.ASICMINER-PT. It pays a weekly dividend.
