This is my personal opinion.
I would try focus on developing a good VB if you can. I never went down the computer road for the same reason of not knowing the gaming law for the different areas. At the end of the day, using a device (whatever constitutes a device) in a casino is more than enough to get you a ban. You may not be criminally charged, but if you are actually caught with an RC, you will get branded a cheat which isn't a whole lot different IMO. Not to mention, if you are the only one betting after the spin, you will get watched a lot more closely when you win.
I'm sure RC's can be good, but I personally won't bother with one for solo play in North America. Having said that, I know there are people who do use them in NA casinos. I just have a vagina when it comes to using RC's in casinos. lol
