I'm not against people importing, and I can understand why people do, but personally, I don't for a number of reasons,
1) I want to support the UK industry
2) UK titles are often cheaper
3) You can guarantee you won't be hit by import fees by sticking to UK releases
4) You know Region 2 discs will always 100% play on your machine
5) I can stick to what's being covered in UK anime media (websites, magazines etc.)
It's kind of self imposed, I suppose - I like the regime that sticking to UK only releases afforded me - if I opened myself up to international releases too I'd probably go crazy and just try and buy everything, and I already buy too much as it is.
