i have a couple jalapeno's and a 10gh blade as well as a 336mhz usb and a yellow jacket 2.1Ghz usb miner for sale. all working. i know its all old but make me an offer. i also had psu cables made for the jalapeno's the blade has never been used i bought it and then never got around to wiring it up.
Hey OP!
My gut reaction was echoed earlier when someone suggested an S3 to get going. If you bump your budget just a bit that is certainly doable. Fair warning... if you are looking to get into mining and learn and have a quirky little farm that needs setup and maybe some supervision? Something like dethdeks offer above would give you several different rigs/pieces of gear to work with.
Why is that important? I'm an idiot, yet I managed to acquire, setup, get online and run an S1 farm last year. When I got my first S5 I bet myself from starting to unbox to having it up and running would be under 5 minutes without looking at any directions. I did it easily. Again, I am a moron with computers.
Be warned... either route you are not going to be raking in the coins. Still... it is fun as all get out. Good luck!
