Thanks, I can wait for the group buy. I'll stay subscribed to this thread if you post it here.

An externally hosted image should be here but it was not working when we last tested it.

Sorry for the poor images, dont really have good lighting in here, and not so skilled with the camera.

just a tip
turn off your flash on the camera and use the light above/near you. You could also try to tape a piece of paper over the flash so its not reflective.

looks nice .... how many you got there?

Took those photos in my room, which is kinda dark, only got a single incandescent light on the ceiling, and it was already dark outside, so the flash was necessary. What you see is what I got, 6 boards, 4 for BUF634u or OPA551, 2 groundplaned, 2 not, and 2 boards with groundplane for Intersil HA5002 buffers.

Looks very nice. I'm in if you get a GP rolling. I'd like to put together a more proffesional 'ChuMoy' than what I've now (it's a P2P mess, works well... but not very portable) .

Those look pretty decent. Hard to really tell until you start stuffing / soldering, and whether you find any hairline cracks etc.
Better than home etching, anyway. Maybe I'll give Olimex a shot sometime in the near future.
