I think I might try "Electrum" as lots of folks are recommending it. I'm sure I'll figure out the "Keys" part when it comes up.
Thanks!

 I'm concerned on a number of issues the main one is loosing money. I'm not really investing money in Bitcoin but using it as a means of payment. $500 worth. Does a different wallet really download quickly? I am five days into downloading Bitcoin Core Wallet and it isn't 50% done and it says 2 more weeks which will probably get longer the way this has been going. All this is very new to me and I'm taking a leap of faith to get this working. I still haven't made it to steps where I buy Bitcoin or spend bitcoin. This is kind of nerve racking. I definitely might not be cut out for this. Trying to conceptualize all this from start to finish when I haven't done this or seen it done, well I'm sure you know.
