Josie:

I use Sonar Producer, which is nice but kind of expensive for the initial buy-in.

I got my brother started in Reaper and he's up and running. It's an amazingly powerful, flexible and affordable program. But, to me, it didn't seem to be as intuitive as some other DAWs. But there ARE a lot of good tutorials, manuals, wikis and forums to find out what you need to know.

Another DAW you might consider is Mixcraft6 Pro Studio by Acoustica ~ $ 149. http://www.acoustica.com/mixcraft/compare.htm

Electronic Musician magazine named it one of the best pieces of musical gear of 2013. http://www.emusician.com/emusician/0765/the-best-music-and-audio-gear-of-2013/152486

Mixcraft 6 has several different levels, depending on how many plug-ins you want and Mixcraft 6 Pro Studio has 18 more plugs than the $75 version, including Izotope Mastering essentials https://www.izotope.com/press/1.20.2012_iZotope%20Introduces%20Mastering%20Essentials.asp
and some reverbs and eqs.

I don't know how well it works with drag and drop from BIAB or RB, but you could download a trial and see.

Some ideas for you to think about.
