I got out of the 1099 business when the NEC was resurrected.  Clients use efilemyforms.com.  Last year's pricing was around $5/form including efiling with the IRS and mailing recipient copies.

I have a handful of clients who only issue a 1099 to me each year (no other contractors) so I signed up for IRIS to submit those directly to the IRS in January.  We'll see how it goes.
