Hi,
What is your aircraft type? You might also consider Bodmin and Perranporth. They both have friendly, active Clubs, are licensed and give much easier access to your aircraft. They are likely to be cheaper than Newquay. Perranporth has the advantage of 3 hard runways (no waterlogging). Unfortunately, Lands End airfield not only suffers from waterlogging, it also isn't apparently accepting any base private aircraft at the moment.
The only downside to the above is if your aircraft is Diesel powered. The only Jet A1 in Cornwall is at Newquay.
Cheers,
