I use either CPC or Farnell to get my caps (farnell has a bigger selection but has a £20 minimum spend to pay by card, and i normally order £5 - £10 of supplys)

I favor stock Panasonic Branded SMD's these days, either that or ceramics

And Uni's drives are pretty good, deffinatley worth getting one (I suspect the adapter you have MJ313 may be one of the ones i make and often swap with uni for cool stuff, if it has built in termination it is one of mine )
