If you don't mind watching them on your computer, you can reset the region of your DVD-ROM reader to region 2 and just buy your DVDs from Amazon.com in the UK.
If you get into watching films on PAL DVDs, you'll find that you get more resolution and non-interlaced frames...
Plus, oddly enough, I have found that the movies that I like are actually cheaper in the UK, even when you include shipping.
That's funny. My software warns about setting the region X times before it's "permanently" set.
So it you don't know much about codecs, alternative software, etc., that may not be an option for many people.
