Contact your siemens rep and ask to quote a trainer unit. It's what Siemens uses when they put on training. You may be able to find a used one at a reduce price.

There are also some digital simulators that have switches on the input card instead of real inputs. I have one and use it a lot when doing S7 programming.

look into the S7-1200 range

cheap and use the same concept of OB/FC/FB/DB etc so ideal to learn the basics before stepping upto the S7-300 /S7-1500

Call your local Siemens rep.
They do sell "Starter kits" for their lines.
S7-300, s7-1200, etc.
Some of the starter packages for the S7-1200 series come with an hMI as well. A bit more money though.
But you get the hardware and a registered copy of the software.
