That Stereolab/Nurse with Wound record is a tough one to find without spending an arm and a leg. I'm happy enough with a digital copy to not splash the cash myself, but it is a really good listen.
Stereolab were one of those bands whose commitment to vinyl was almost legendary - they convinced me to continue buying records for longer than I intended.

Never heard that ISAN single, but their Lucky Cat and Plans Drawn in Pencil albums are a couple I really like and come back to listen to quite a lot over time.
I really liked the early stuff from Isan. I'm pleased that somebody else here has heard of them too.
I have earmarked that Damil 85 / Cubillo single as one to go. If I'm unable to sell it, I would be more than happy to send it your way if you wanted it.
