I typically don't buy a book until I've had a chance to read it first. My county along w/3 others has ALL of their material listed online, and I can go online to search and reserve whatever I want and then have it sent to my local library for pickup--all FREE, and typically takes only a few days.
You may want to check in w/your local library system too, as they may offer something similar. Doesn't cost a cent to check out a book and you'd be surprised what is on the shelves sometimes.
That way, you can take a look at the book and if it doesn't appeal, back it goes. If it opens doors for you, then you can search it out on Amazon or Thrift Books online for cheap.
Along the lines of not being happy w/your meetings, you could try the chat rooms here at SR, or online/phone Alanon meetings, too.
