Provided you have a little extra spare cash, I'd always recommend buying a share in an aircraft and flying in the UK.
I'm flying a PA28 - my wet hourly rate is less than hiring an a/c in the US or Canada, and will have spent about the same amount of cash on hour building as someone going abroad. This is because I'm not spending money on airline flights, accommodation and all of those extras that are suddenly needed when you pack your suitcase.
I do however, contribute a montly payment of £50 to the group, meaning at least 4 flights per month must be flown to keep it cost effective.
What about when I'm done with my hourbuilding? Sell my share - a/c shares keep their price, I'd have lost nothing.
In return you gain the ability to keep working. Flying can be arranged with great flexibility in a small group, and ATPL swatting can be done during the evening.
Job done!
