As Si said you won't be disappointed once you get your car all set up, they are excellent cars to drive and I really like mine. When you get it though, probably worth checking the belts and in doing so you'll appreciate the work involved in changing them. I bought two second hand cars, one as a spares donor, and put all the best bits together, but the mistake I made was not replacing the belts and on my first meeting broke 3!. Look around on ebay or here and get some belts and pulleys so you get it all set up right initially. Also, make sure you get the slipper all set up right so there isn't too much strain on the belts. THere is a mod that some do cutting the main belt cover (see review on here) but it can mean a bit of unwanted flex so i don't cut mine, I just sware any time i need to access the transmission during a meeting!
If you're not sure, go for a B44, they are a little more user friendly...what am i saying, get an xx4 and a good set of allen wrenches!
