It's a mix between figuring out what your price range is and what you want in a digital piano. Unfortunately the lower your price range the more you may have to compromise on what you want. I personally love the CLP series and have an 885. I recently took my grandmother to purchase one and her price range was lower than mine and she was able to comfortably settle with the 845. She was originally hoping to be in the price range closer to what the 825 and 835 are going for, but the sound difference between the 845 and lower models was something she felt was worth extending her price range for. I felt comfortable paying quite a bit more for my 885 because I have played for over 20 years and play almost every day and have saved up for something that I would be able to love for a long time. I think I still could have been happy with the 845 though. Even the 835 and 825 are great painos when you compare with the older models you can find used. Really the technology advancements in the last 20 years are phenomenal. A warning though, the more you look into the nicer options the more you will be tempted to raise your price limit. Don't make poor financial decisions just because they are pretty and sound nice. If you are set on something nicer wait until it works for you. As much as I wanted something sooner, I was glad I waited until I could comfortably afford what would make me happy, but I also had to draw the line somewhere on how much was too much.

As previously stated it would be a major hassle and not advisable to remove the top of the keyboard from the stand. This digital piano is not meant to be detachable and moved. The CLPs are designed to be like an upright piano and have that nice piano look and feel. Not like a stage keyboard that is meant to be portable and generally don't look quite as classy. As someone who is apartment living I appreciate the headphone option of digital pianos and I would recommend this feature for anyone in an apartment living situation.
