If you want into bitcoin, just buy the damn things. You just missed a solid opportunity, though.

If you want to mine, like really mine, go with altcoins. Many are profitable right now, so much so that you can't buy a 280x or higher GPU for $200+ over launch price. It's always possible to trade and add to the BTC stash with altcoins, a lot easier than buying with fiat.
And the hardware you buy will depreciate at a much much slower rate, especially if alts keep climbing relative to BTC. The supply chain has been hit hard lately, if these trends continue and the hardware supply stays the same scrypt difficulty can't possibly grow as fast as BTC. You'd be doing good to have GPU hardware around in that case.
