Unusual hour building? Well, then, you might consider France or Spain. The plus? No visa needed, all JAA i.e. no conversion required, just a basic check flight like you would get in your friendly UK aeroclub, and off you go!
Hour rates are also around 25% lower than in Britain, so you can plan the odd long navigation without breaking the bank.
I only have first-hand experience of hour building in France, and there is a lot in common with the easygoing yet professionnal attitude to flying you find Stateside. Very few airfields have landing fees (owned as they usually are by town/city councils), there are often bars/retaurants on site, and language-wise, you only really need to speak French if you fly to an uncontrolled airfield, or to a controlled airfield outside HJ. French ATC is quite good at English, and so is French MIL ATC when you need clearance through MIL-R areas (there are quite a few).
I used a PA-28-160 for 107 Euros/hr wet (that's just under £67), or a PA-28-181 with the full kit for 122 Euros (about £80). The club also had 2 Robin DR400 that went at 90 Euros/hr wet (£60). These prices are pretty much standard. The only downside as far as I am concerned is that the joining fees are higher, usually around 200 Euros for the yearly membership (£120), but obviously that depends on the club and with the lower hourly rates, it gets interesting the more you fly.
Regarding Spain, a search will help you find more info. I only know that hour building prices are also about 25% lower than Britain, and you do get lots of VFR days even in autumn!
Hope that helps
Cheers
