There's an Aztec at Bournemouth if thats not too far for you to get to. The owner has a website with all the details on it at <a href="http://www.tidelands.demon.co.uk/" target="_blank">http://www.tidelands.demon.co.uk/</a>
If you want to build hours quickly and cheaply I suggest a short holiday in America, although if you have less than 50hrs multi you may have trouble with solo rental. Some years ago I found American Flying Adventures in Florida willing to rent me a Seneca when I had low hours. They also have a website at <a href="http://www.amfly.com/" target="_blank">http://www.amfly.com/</a>
Hope this helps and good luck!
