The only thing of caution regarding the Scrambler would be the suspension. It's horrendous (all stock Bonnie variants are lacking). The power is plenty enough though nothing like a super bike, which I'm assuming isn't a concern for you. Second to the suspension, is the truly awful seat- it gets damned uncomfortable after a 100 miles or so. Plan on spending about $100 to get the seat modified.
I used to feel the same way having owned a carbed Bonnie. Since picking up and working on my '12 efi Bonnie and tuning it with my laptop in 10 minutes, needles and jets can suck it in my book.
