As we discussed earlier on MSN...................
Bluefins are excellent if you want an off the shelf conversion that is easlily reversed come service/warranty time..... its DIY takes about 10 mins to install / Remove..... you get a 7 day trial - so you can try it out and make sure your happy with it, if not you get a FULL refund.... they even include a freepost label

You get a piece of mind warranty should you ever have a problem that is due to the bluefin being installed you have cover...... (subject to there terms and conditions that can be found on there website
www.mybluefin.co.uk )
Ive done a couple of the ST's and i'm sure you wouldn't be dissapointed
I also offer a healthy PF discount
