Hi Rachel, I had a combo recumbent elliptical/bike exercise machine that was reasonable priced and worked great for both purposes but I recently upgraded and got a Teeter FreeStep LT1 because it is more of a crossfit trainer and better for upper arms, shoulders and legs. Also the leg motion is more closer to walking than using a standard elliptical machine. Teeter has a lot of great instruction videos for targeting different muscle groups on their website. I'm also thinking about one of their Fitspine inversion tables. I had a really old cheap one that I gave away because it was difficult to adjust and bring myself back upright.
