Don't know about the UK, as I am in the USA. But as far as prices are concerned, I seen these two sites have the lowest:
Mouser: http://www.mouser.com
Questcomp: http://www.questcomp.com/Index.aspx
And not necessarily for caps, for they got them, but go other parts like connectors-
Digikey: http://www.digikey.com
As for the cap type, Tantalums are electrolytic as they are polarized, but the old fashion cans will leak in time, so if you can get the solid state Tantalums, that would be fine. Tantalus come in Surface Mount Technology squares or in round tiny beads with long leads you cut to size. Genie_Mac did his SE/30 with the beaded Tantalums and it looks great! His page of him fixing his Mac SE/30 is here, it deserves a look:

BTW - the Beaded Tantalums are far cheaper than the Surface Mounted Squares if price is an issue.
