Play fair Mono
Not sure where he gets his £4 a day from, but it is mighty cheap compared to club/school rental rates when spread over a period of time.
I recently did the sums and over a 5 year period it would pay me to go for the type Mono is on about, even on group rates - unfortunately the recent ex has put paid to having a whole one to myself for the time being.
Hence my appeal for anyone happy to go halves!!
Obviously we can't reveal the type or everyone will want one
