Oversteer
I'm a Peg owner and currently pay about £750 per year for insurance, but that's with 480 hours and a Basic Instructor Rating (but add back in a loading for a rather silly and expensive ground handling accident a couple of years ago). Annual inspection and ARC should cost around a couple of hundred quid or so a year, and then there's the trailer parking fee of between £100 and £300 depending where you fly from.
Insofar as flying a Peg is concerned, as long as your speed control on approach is good there's no reason why a Pegase or ASW19 should be beyond your competence, but check with your CFI and try and fly a club one somewhere (eg Gransden Lodge) before you commit. My former syndicate partner had much less experience than me and coped quite adequately with ours.
Caught me on a good day, as I did my first 300km in 4 years on Saturday, and shaved 45 minutes off my best time for the distance
Cheers
