Useful site, handy for looking up board-pulls! I use them quite a lot, not just mosfets but bipolar and other types too. The specs they put in the boxes aren't always accurate though - always check the data sheet!

I always use components101.com it has been a lot useful especially when I have a handful of IC's which I have not used before.

They provide pinouts, specs, alternatives, application circuit explanation, usage tips etc.... but for some series designs the information will not be enough and I always have to download the datasheet which is also provided by them

I use "tme.eu".

I got my multimeter from them since Brymen meters weren't available in the UK at the time (at least not to Joe Public), sent from Poland, also some relays I couldn't get elsewhere. They are very good. Now have offices in the UK too!
