If you really want to host your own server for incoming mail, SES would probably be fine for SMTP and very cheap. With things set up correctly (SPF, DKIM), my personal experience with deliverability has been problem-free. However, I've seen others say they've still had issues because of the SES IPs. For double-checking the quality of your setup, mail-tester.com is handy.

If you want to migrate to a free consumer service (like a personal Gmail account and using aliases), a forwarding service that also provides SMTP is an option. I've been testing Pobox.com and it looks great ($20/yr for up to 20 addresses). I first tried using my registrar's forwarding service, and sending from aliased addresses via the Gmail SMTP Server, and had lots of trouble with deliverability, so I wouldn't recommend that.
