if speed is not critical
Purchase cheap mobile phone and Use DTMF based trx-rcx. This will give unlimited range

You may try RFM12 transceivers. Seem easy to program. Available on RI store.
I tried to buy a pair but didnt hear much from RI expect a few mails. So finally bought CC2500 from sunrom.

You might also want to checkout xbee (or is it zigbee) modules. Will have to search for a good deal though.
