Crucial UK are gradually reducing their rather inflated prices. Their 4GB kit is now £211 including VAT. It was £336 when it first came out and then dropped slightly to £272. It still has a way to go to match OWC (which is around £150 inc import/VAT I think) but it is getting closer. This may be of interest to UK people who don't want to import (ie me - though from what people have posted, importing is pretty painless except if you need to return the RAM as faulty).
