Implementation ideas for software defined radios

Question

I find Software defined radios interesting, and was searching for ways to learn about it.

One way is getting your feet wet with devices like USRP products.

However, USRPs are rather expensive.

What are alternatives/less expensive suggestions for getting a software-defined-radio implementation?

I would like to use it to eventually build things like a GSM base transceiver station, etc. in a budget-friendly way.

Then you'll have to wait a few years. Right now even the "revolutionary" [Per Vices Phi](http://www.pervices.com/support.html) is $750. — mng, Sep 03 '12 at 16:37

One way is to use for this purpose cheap USB TV tuner. I've read that ppl have good results with it. Here is the link:

Obviously it is viable only for receiving (so no, it is not possible to make GSM base station with it).

However GPS receiver is doable:
