These are the only two I don't have. At audiodeluxe these would cost me $69.41 (with my measly $0.94 in DeluxeBucks, and points on my CC). So I went for it.
I have these.
I was going to suggest the 2-CH Warm audio unit but it's $100 more.
On my side I want to add 4 more mic preamps and have my sights set on this one: Warm Audio WA-412 4-channel Microphone Preamp | Sweetwater
$300 more than the Focusrite ISA 2 and I get two more preamps.
Hmmm I tried that with a pedal I already own (I own them all) and it wouldn't take.
Cest la vie. I already own Buxom Betty from UAD so it's not worth the fight.
