If your registered, which is free to do. Get the equivalent to the VAT off clarke tools from Machine Mart (10% on all most other stuff). If you are VAT registered or have a frend that is, you can still claim the VAT back as well, doubling your discount. I bought a large compressor like this a few years back. I am in no way connected to Machine Mart, but just got my reminder email and thought I'd share. I would add that it is still important to check prices against other suppliers. You may be able to buy cheaper elsewhere without any discounts!
Might just be at your local one dude... Mine had one about a month ago But I will give them a call to check
