Thanks for all the replies. I'm thinking of trying the tempest, don't think I've got the stamina though.
Tempest will be rather tricky: it's on the LRSM syllabus, I guess it depends if you're looking for something to make a real polished performance of (in which case avoid Tempest for a while yet) or just something to have a bash at for fun not minding if some bits aren't quite as good as you'd like. If you want something you can stand up and perform proudly Tempest is probably not the right thing for you at the moment; if you like it and just want to have a bash then there is, of course, nothing stopping you from doing that.
Op. 49, No. 2 (No. 20) is generally regarded as the easiest sonata, in two movements each of which isn't much harder than grade 5 (my estimate) although learning the whole thing will make it a bit harder. If you want to do a whole sonata I think the only other one with all three movements sub grade 8 is Op. 79 (No. 25, Alla Tedesca) of which the first movement has been on grade 8 and the third on grade 7 (the second is easier than the outer ones). There's quite a bit of three against four in the last movement so you'll need to be good at (or learn to be good at!) that. Although all the movements are sub-grade 8 it's harder than playing a grade 8 piece to play the whole sonata because of the sheer length (it's like playing two for a start!) and keeping the whole thing coherent.
The Pathetique would be rather difficult at grade 7/8 standard, in particular the first movement with the sustained tremolo requires a lot of stamina. It's quite a popular work too so if you play it you've got to play it well. I think you're right to steer clear of that one, especially as you're familiar with more of the sonatas: take advantage of the fact that you're familiar with, and like, more than just the standard few that most people explore and be more adventurous, whilst taking in all the great music that so many people sadly miss. I used to really like the two most famous sonatas; now I still do like them but they're nowhere near the top of my favourite Beethoven Sonatas list now that I know them all. Unless you really want to learn a whole sonata, perhaps a few 'odd' movements would allow you to explore a bit more material at the appropriate level: learning a whole sonata would be a great experience it depends if you feel that you can manage the one you want to do.
As for buying a volume of the Beethoven Sonatas if you're only getting one I'd advise that you get the first volume: there's a general trend in increasing difficulty as the numbers go up (although there are certainly some that don't fit the trend). The sonatas really start at dipABRSM level with one or two exceptions so none of them are easy, the first volume would however be a good place to start with some single movements as there are quite a few manageable ones.
My personal favourite (it's hard to pick one but I think I'd go for this one) is Op. 28 (No. 15) it's not on any of the dip syllabuses, my guess is that it's about dipABRSM difficult but is a little too long to fit in a dipABRSM programme with other things, hence it's absence. I could, of course, be completely wrong

I've seen a list of the relative difficulty of Beethoven Sonatas (which is, of course, subjective) it's been linked to from here but I can't find it with a quick search. I think it was originally from Pianostreet. If I come across it I'll let you know, in the meantime someone else might have the link. I have a feeling there was another 'easier' one on there, possibly No. 10 or 19 (not sure), but I can't remember off the top of my head.
P.S. There's nothing wrong with being obsessed with Beethoven sonatas
