That's true mad_jock, but the Grob 109 is a pretty good tourer for the hourly rate too!
No reason it couldn't be used to do the 300k cross country though I accept a VOR/DME equipped spamcan might be a better choice. I'd also suggest that "fun gliding about with the engine off" is a good way to improve handling skills which must also help with CPL prep. I'm simply suggesting it's a cheap way to do at 30 hours a bit differently and cheaply ... "more strings to your bow" and all that?
