I had great success convincing their AI chat bot to give me a $5/mth streaming only package for the next year, they called me last week offering to reactivate one of my radios for an additional $1/mth for the next year. There's a few posts on r/siriusxm on reddit where others have been successful in getting good deals as well!

Have a look on GitHub for some scripting involving radios and their special apps, fingers crossed it's still working but you can sometimes get the radios activated for a few weeks at a time.

As for finding hardware, Value Village in Oakville next to Home Depot can be a great place to find really nice electronics. I have a friend who found two XM2go radios for something like $10-20 a piece and still work fine up to about channel 120 or so :)

Pretty much any radio that has an alphanumeric ID should work with any stereo and one of their antennas/vehicle docks. I had used a small 12V wall adapter with lighter socket output to power the dock and a 3.5mm to RCA cable to the amplifier/mixer. The vehicle antenna should work fine if placed outside when you need satellite reception, and often times works indoors in the city with their terrestrial repeaters. The in-home antenna is not water tight from what I can tell, at least the version I had, I wouldn't trust it outside for long. The antennas almost always use an SMB connector and have a built in LNA so other antennas are not going to work, also sirius vs XM/SiriusXM are two different frequencies. Their current SiriusXM system (with channels 120+, about 300) is based on the XM system which is why new radios have alphanumeric IDs rather than long string of digits, and why old XM radios can still be activated and work fine! Though you won't see many channels past about 120 on them, you need SiriusXM branded models that support the enhanced FEC/bitstream format.

One other note to buying used is to grab the radio ID before buying and call or use their website to find out if that radio is okay to activate and not on an unpaid account.

Happy listening, Alt Nation is one of my fave channels :)
