anyone got one of those cheapie SI 4732 based receivers?

[Rob Seastrom]

I've been watching with some interest the SI 4732 reference design plus an Arduino receivers that are showing up in my YouTube feed, available on eBay or Amazon for sub-$75 (for something in an aluminum enclosure with a speaker this is pretty remarkable).

Looks like it might make a good pairing with an MLA-30 mag loop.

Anyone bought one and played with it?  Seems pretty cool for the price.
