Do you know how much a 256GB is in the UK? are all SSD's the same quality?
There are a host of fine SSD makers, such as Intel, Crucial and OCZ. Most recent models are brilliant. In real life use, you may not notice performance differences. All are silent, tough, and awesomely quick compared to HDD's - especially in reading. What you will notice is what size it is (if it isn't big enough), and the price you pay. Intel has probably the quickest product overall but is restricted to 80GB and 160GB. Other big makers such as Crucial and OCZ have 120GB and 250GB as most popular sizes.
Have a look at a few reviews:

Crucial make excellent SSD's (120GB and 250GB).
Other UK sites like M2M sell a range of Crucial, Samsung and OCZ SSD's (all excellent).

A 120GB is around 240 pounds, and 250GB twice that.
If I could get the latest Intel SSD at a good price, and the right size, go for that. But if you need a different size, get a better price, you should also be very happy with other options.
I have used a OCZ Summit 120GB SSD for 4 months now (the Intel was ridiculously expensive then, and not the right size for me), and am still totally happy with it - as I am sure I would be with most modern SSD's, if size and price is right.
