i like the USRP(n series), Pervices (noctar/crimson), BladeRF. you're
right about price. cost quickly becomes significant!

antennas and front-ends can help a modest radio be better, and here
too a dearth of good DIY information...

and sadly, power consumption is going to come home to roost before
these go mobile. might have to wait for direction conversion circuits
before SDR can be tiny, portable, efficient?  i am sadly short of
solutions, only full of more questions and complaints :)
