If you're looking to make bitcoin then your best investments would either be buying Bitcoin directly (like from
coinbase)or if you want to mine it the gaw hashlets are going to give you more bitcoins faster than buying fury's and a zenminer.
However, if you want some small scale mining hardware....buying a Fury with a zencontroller (or hook it up to an old laptop) would be a fairly cheap way to start. You could also look into getting an old inexpensive BFL jalapeno or one of the newish
Rockerminer R-Boxes. They likely wont make you more BTC than if you just directly bought BTC, but they are fun to play with and show off.
If you want to look really fancy (but won't pay themeselves off) you can buy a few
Antminer U2's, plug them into a nice looking USB Hub, add a USB fan and some blue lights. <---always a good conversation starter about bitcoins when people come over to your house
