I don't have EQ7 but I do have EQ5. I have own two previous versions.
Yes, there is a learning curve but they give you a cookbook that takes you thru all the steps.
Being able to take a quilt I like and getting the design drawn quickly. Resizing blocks are quick and easy.
Only thing I miss is the ability to do more complicated Bargello (remember I have EQ5) and the limited online fabric selection. Both have been improved in EQ7
Depending on your financing, if EQ8 comes out, then people might be selling their used EQ7.
Yes, QIAD is a great place to look. I think you need to put it in your shopping cart to see the price.
Once you get familiar with the program, you can do anything, the sky is the limit. If you want to try paper piecing, EQ will number the sections in order to be sewn automatically in a block. I almost use it every day. Just wish the company didn't take away our ability with EQ5 to be able to download the fabric available monthly.
