Thanks, however - I'm by no means "locked" to Eletrum - any wallet where I can transfer my Armory-BTCs will do. =)
What do you mean locked to Electrum?
There are many wallets but it seems that you've experienced some issues with Armory wallet according to your old post on the Armory section.
Why not, focus on Electrum first because it is one of the easy-to-use wallets.
The important here you already have the private keys that you can use to import your old wallet where your $30 in BTC is located or saved.
As what I mention above the private keys that starts with 5 you can convert them and I'm sure it will work after you convert them into k or L.
