Thanks guys. I forgot to mention that Honda is my first choice just by word of mouth and what I have read over the years.
I would prefer 4 stroke also, because I believe that would be quieter than a 2 stroke as well, and I don't want to piss off the neighbours too much, I believe they are also cleaner burning.
I would be tempted just to jump on either a 250 or a 450...I wouldn't do anything too hairbrained for starters on a 450.
Thanks! I'll follow up if and when I get something!
