Not a lot of engine for the aeroplane, but a lovely aeroplane to fly.
You'll find it a lot of fun solo, but occasionally a bit limiting 2-up.
That said, I did a lot of hours in a 447 engined Raven before the engine died and I upgraded it to a 503, which improved an already very nice aeroplane. My 447 engined Raven used to burn around 8 litres/hr solo, 12 2-up.
Sooner or later the engine will die on you. And unless you've fluffed your training completely, you'll calmly land it on a pocket handkerchief, get a lift home to get the trailer, and just chalk it up as another flying experience.
When you get past about 250 hours on the crankshaft, investing in a Skydrive "conrod bearing tester" is a really good idea to monitor internal wear. And don't skimp on oil - pick a good variety and stick to it. Silkolene and Shell Advance VSX 2-stroke seem the most common "good" oils.
And be aware that the most expensive bit of the aeroplane is the sail. Look after it, and minimise the UV exposure.
