Hi folks
Although I have a Genos which I very much enjoy using,I had a desire to buy a much cheaper and lighter keyboard to move around between rooms when required.I watched some youtube videos and read user groups views of keyboards and came down in favour of a Casio CT-X5000 which seemed to offer everything I wanted at a very reasonable price.The voices are pretty good and many styles are very usable,the thing I am not happy with is the difficult,clunky and quirky operating system which seems so much harder to use than Yamaha OS,ie.so many button presses to achieve what you want,but I don't want go into all the dislikes.
I have only had the keyboard a few days so it is still possible for me to either change it for something else or ask for a refund.I am very undecided whether to give it more time or to change it for a Yamaha ,probably a PSR E463,I unfortunately cannot go to a SX700,which seems a very nice keyboard.
There is perhaps another option available to me,a very close friend has a PSR670 which she hardly uses ,she just cannot grasp music or the operation of the keyboard and I think she would sell it to me if I asked nicely

The psr670 is about 3 years old and is as new,how much should I reasonably offer in £££'s please ?
Needless to say, with having a Genos I am now spoiled by the easy OS of Yamaha keyboards,I don't think I am going to adapt easily to another make of keyboard.
Your thoughts and opinions on this will be read and valued as I trust you knowledgeable users to give me some valuable advice.
Thanks in advance
Alan
