Little tip for UK users - if paying with mastercard, paypal still only gives you their own crappy exchange rate on GBP, if you choose to pay in USD then you get charged mastercard rates which are slightly better plus a small exchange fee... not so viable on smaller orders (under £20 for example), but anything above you can save a few pennies (pounds).... dunno if this is true for other countries / currencies too, but might be worth checking for yourselves
