Yamaha Digital Piano

Hi Graham
 
I would just like to say that I found your website very intresting and informative and have enjoyed reading peoples questions and your advice.
 
I have a question about the Yamaha Clavinova. I'm a beginner and am thinking of buying the Clp-240 or Clp-340 digital piano ( hopefully in the not too far future), is it one of the best for beginners? I'm mostly intrested in the touch as I would like a piano with as much realistic weight behind it so I can build up the necessary finger strength etc. I just wanted to know becasue someone reviewed it on your website but said they had some difficultly adjusting to their teachers acoustic because their Clp-240 was lighter. Would you still recommend this model? as I dont really want to go any higher up in price. Also are this things made to last? can they take a lot of practing on everyday or will the keys become loose or wear out fast? Oh, and lastly what is the diffrerence between the Clp-240 and 340 how has it been improved, I cant seem to find any infomation on its specifications.
 
Thanks
