Also, what country? Shipping can get expensive if international. Besides DIP or SMT, is there any brand preference like Ti, Motorola, etc? I ask because I probably have at least 3 of those 4 in DIP, all socket pulls...

Well, shipping from Canada would cost a bit I think, even a padded envelope. If you get no other replies, get back to me and I'll look for the other chips, I have 8 of the 74LS21N so far....

All those are available from Farnell electronics at around 55p each except the 153 at about 80p

The total for those and a couple of the RAMs you want would be under a tenner, plus post.

For reference, Rapid Electronics are reasonably priced for delivery at around £4.80 per order if under £30. RS is £4.95+vat for delivery so still not horrendous if you can make up the order with some extra bits you might need in the future. CPC is £3.60 including vat for delivery of orders under £20. I doubt any of the above are making much profit out of you considering a small packet costs around £3 to send via Royal Mail (plus the packaging)

Have sent all the LS chips, and some SOP SRAM's to 777xxx guys, but if anybody still has any 32k x 8's in DIP, I'm sure he'd grateful to receive them.

I have all of the above except the 74LS08. I'm pretty sure I have some somewhere, but I would have to dig a little more. I'm in the US though, so I'm not sure if the shipping would be worth the parts.
