I've been using the 70-200 at first.
Next few are with the 100-400 which gives me more distance, and allows me to use the 580EX.

#1 looks like an Oak Bsuh-cricket, but on buddleia ?
#2 Red Admiral - finally a good upperwing shot
#3 Peacock
#4 Common field grasshopper


and on the other question...

Remember there is no warranty service on lenses bought abroad.
Unless they happen to be UK stock, which is pretty unlikely.
It may be different with CPS membership, I haven't asked.

If it's shipped to you, then there is a good change you'll have to pay import duty and VAT on top of the price. Assuming that it gets inspected on the way into the UK.
Also when filling in the CN22 customs declaration a value of $1200 cries out "steal me" on the way to your house.
So it has to be shipped insured, and preferably signed for on delivery.

By far the best idea is to fly out, have a holiday, and buy it while you're there
Then you can carry it back with the rest of your gear.
