What is the handheld SDR and where can I buy one?

New PortaPack H2 And HackRF One SDR Software Defined Radio (check Banggood)

Looks like maybe a custom case, but 99% sure it's this hardware that has been customized.

edit: Actually you can find the exact model they are using on eBay...just google the first line of text in this comment.

And how much does it cost... if this is cheap, it seems that insurance rates on Honda/Acura vehicles are about to increase.

Looks like a HackRF. About $350 + knowledge of how to use it and leverage the attack.

The HackRF or similar SDR is useful for creating a prototype, because they work across many frequencies and can modulate and demodulate essentially any modulation scheme in software.

Once you know that it's, say, 9600 baud FSK at 433MHz, you can buy a transceiver IC for a few dollars that can send and receive that frequency and modulation, and drive it with a microcontroller.

I wouldn't be surprised if we start seeing such devices on AliExpress for $10 within a year or so.

Can you comment or recommend any resources on the legality of owning a PortaPack H2 in the US? (eg. is an Amateur Radio License required?)

I'm not a licensee but it depends on the frequency used and the power.
