I'd recommend Bedford for a first trackday - did the last RMA day in December and it was great!
Only problem was that I obviously hadn't bedded the brakes in enough (even after 2500 road miles!) but they more-or-less survived [img]/fckeditor/editor/images/smiley/MWPX/confused_smile.gif[/img]

Many insurance companies offer free or reduced rates for Porsche Club days, which helps to offset the extra expense of the day. I'll certainly be doing several of them, once they publish their calendar.
