peace, my friend. peace.
The fact of the matter is this - Liszt is really not that easy a composer, so unless you bring the skills to the table, you are in the wrong restaurant.
...im not sure if what I just said makes any sense (gimme a break, it's late here), but what I am trying to say is I dont think there is such a thing as an "easy" Liszt piece. Some have their own individual technical issues that just take time and patience, but Liszt was a great pianist; he didnt compose anything impossible (In exception of his very early stretching - maturity works which do not appear to be made for human hands).. therefore all the pieces are of the same difficulty - that is, they are all "possible" to play. I think it all just depends on how much time one piece takes compared to another. I cant believe Im saying this - it must really really be late here..
The difficulty in all of Liszt usually lies in phrasing and interpretation. (esp in the later works). If you want technically less challenging, but musically formidable works, have a look at liszt's late works (circa 1880) such as the Forgotten waltzes or Czardas Macabre.
Dont attempt any of his mad virtuosic stuff from circa 1840 unless you are ready to practice and work like a dog to do the piece justice in the way it is intended. These pieces are designed to bewilder the masses and charm ladies into the bedroom. You dont do any of the above by cheating and simplifying.
By the way, I also played Tarantella. I didnt find it too hard in terms of learning notes, but actually performing it in front of a crowd is really intimidating because my adrenaline, more often than not, boils over and I lose control. For me, that is truly the difficulty in such a piece. (I cannot say the same for Chopin, now..)
