It looks like I just wasted my time giving you a private message on the etudes. -.-
Not likely, anything learned is valuable. While subjective, I didn't think you're assessment of "accessible" etudes was wrong. Just not appropriate for the OP right now.

@qpalqpal - Incidently, if you are not aware..
The Inventions are actually composition studies rather than just a collection of pieces (though I suspect you may have discovered this).
There is a great deal of information available on the forum about them, and bach intended them to be learnt in a specific order, 1, 4, 7, 8, 10, 13.. to get you started (should keep you going a while if you do all of them [ not compulsory obviously

] )
Aside from that, if you're looking for a study.. there is heller, as I mentioned before. Op. 45/47 you can find scores for these at IMSLP. 45/9 infact (and I can't believe I find myself saying this a 3rd time on this forum in only a few weeks) is remarkably like chopin 25/1 (probably based on) but far easier.
here is the set -

Clementi - Gradus ad Parnassum
Hummel - Op. 125.
These are 2 more sets of etudes that will pose a challenge, and may typically precede Chopin etudes in a balanced program of study. There is also a old buried thread floating around somewhere than contains a gigantic list of "etude sets" ranging from easy to obscenely difficult. You may be able to locate it with the search function.
Chopin etudes are not just technical etudes.. you don't just fiddle with them to make you a better pianist. They are advanced concert repertoire. As musically involved as they are technically, and while you may get through the notes, a quality performance of them will take a very long time and far more effort and thought than you will previously have even considered possible. If you're happy with a half effort, fine, go for it

..but if you want to be able to play them like a professional I suggest you better prepare yourself.
