I'm spending a lot of time learning the AVR microcontroller. Its time to spent a little cash on a good AVR book. Anyone have any experiance with these two books, or others I may have missed, good or bad. I'm especially interested in an have the STK300 with a ATmega103L and in the near future purchase the STK500 with a AT90LS8535. I leaning toward the first one because it is 2 years newer.
