Cheap Reader/Writers for Mifare classic cards

whats the cheapest RFID card reader/writer I can get for Mifare classic cards? I have some Mifare Classic RFID cards that I want to have the ability to read and edit.

but Im not sure what Kind of hardware I need.

I think the Mifare classic is a high frequency card so I would need a
13.56MHz RFID writer, but im not sure and they seem expensive.

I just want to have a bit of a play around so i don't want to spend big bucks.

any ideas or help welcome.

Can an Oyster Card be hacked? As i was leaving the tube yesterday a security guard scanned my oyster card with a handheld device just before I was about to scan out through the barrier.

This made me wonder why?.. what was it his handheld scanner would show that the normal barrier scanner couldn't pickup. The only thing i could think of was that somehow oyster cards can be faked and he was checking the status of the card against the main central database.

Oyster card?
if your wondering what an oyster card is.. its a new contactles smartcard that you use instead of a normal ticket on the london underground. It uses Philips' MIFARE Standard 1k chips provided by G&D and SchlumbergerSema. It is the same contactless smartcard as Touch 'n Go card in Malaysia which is mainly used for tollway fares.
