snoring I am a bit confused about how you can have the latest one but not the precision plus. I spent aaaages researching it before I bought mine, and it seems like all the most recent ones had it (2003, 2006, 2008) -it's basically just a facial attachment, and worth it I think, although if you're not going to use it on your face, then obviously not. The 1999 and 2004 don't have it, but they are quite old now (those are model numbers and not the year they were released btw).
Ilovechoo - I think the one on offer at boots is the main one sold atm (2006/11) - as far as I know it hasn't been sold for the rrp of £450 for years, maybe when it first came out. I watched it on boots and amazon for a while and it varied between £295 & £350 each week on both. It only quotes that price so the deal looks better!
I have that one and paid £295 for it and am really pleased with it, but I would probably buy the cheaper compact one now if I were to buy it again, and save £100. The only difference seems to be the number of flashes (but then again will it last for 5 years anyway?) and it does seem to take slightly longer than the larger model.
There is a link at the bottom here which compares the recent models

I also got mine through topcashback, and used boots vouchers, so got back an extra £20 and then £10 or so more in boots points, if that's any use to anyone!
And whichever model you go for I would definitely recommend!
