I know that S4 can now be preordered in the UK and I finally was able to start getting back on track and I purchased S1 recently.
Gorgeous, just gorgeous looking (and it's a rerelease set with none of the issues of the original release) it's truly like watching it for the first time properly almost. The episodes themselves all wide ranging in quality (even though I do have a personal fondness for S1 more than many) but it's totally worth it.
