L A,
No sorry, i'm actually at Stapleford Flight Centre, a training organisation i can thoroughly recommend.
I did about 10 hours of PPL at Multiflight though while I was at university, and it seemed fairly well run. Maybe a touch on the business side of things, but I imagine if you were a 'known quantity' (unlike me trying to squeeze stuff in here and there) you might fare better. Staff seem friendly.
Make sure you budget for landing fees at Leeds though, they can get quite pricey. Also, as they now only work with one runway it got a little congested at times for VFR being held while Mr Boeing flew in. At the end of the day though a few minutes here and there didn't bother me as i'd have to hour build anyway.
