Del, your going to get opinions about bike and stuff that will vary from personal experiences to geographical locations of where the riders live.
I will give the following simple advise.
If you have not taken a MSF or Rider Education course then do so as soon as possible.
Wear the basic protective gear, such as a glasses, helmet, gloves, boots, long pants and armored jacket. There is a bunch of stuff out there and a lot of it is good stuff. Prices vary greatly, but for the best bang for your buck, I like Joe Rocket accessories.
As for what bike to buy. It's simple. One that you can sit flat footed on, and when you sit on it and take it off side stand, it doesn't feel so heavy that you think it will fall over. I would buy used, odds are you probably will drop it as a new rider, and I would rather drop a used bike rather than a new one.
The best experience is time in the saddle, but experience won't get you out of everything. When riding always be prepared for the unexpected.
Now do my opinions mean anything, well, that's for you to decided. I currently own three bikes, one being a trike. I have traveled around a million, and yes I said a million miles on bikes, and all my riding is pleasure. I do not do any commuting on them. I have ridden in 49 states, most of the provinces in Canada, and a bunch of Mexico. My favorite pass time is riding, and I play Aces High when I'm not doing that. For the last 30 years my life has revolved around riding and traveling on a bike. It is a life style for me not just a hobby. Just for the record, and I have nothing against them, but I do not ride a Harley.
Just my Opinions,
Fred
