Every major ISP I've dealt with has been willing to accept routes
advertised from another provider as long as it was pre-arranged. In fact,
in a post-CIDR world that's exactly the way you're supposed to approach
multi-homing if you're not a service provider yourself.
As long as the originating AS is valid, other ISPs will accept the
advertisment just fine, the catch is in having a Tier-1 provider accept
routes for networks it "owns" from other providers elsewhere in their
backbone. That takes arranging, but I haven't met a Tier-1 or Tier-2 that
wasn't willing to do it.

Yes, you most certainly can dual home with a valid AS and netblocks
smaller than /19s.

If you think PSI doesn't have more routes, peering agreements and presence
at exchange points than a regional ISP you've got some learning to do.
I always try to multi-home to at least two providers with at least two
wireline carriers and two entry points into the facility. Even when my
primary wireline carrier gives me dual-pathed SONET. Sometimes I even try
to cross-home address spaces from both providers to one another under
different ASNs just to completely remove any chance of single-pointedness.

I'd sure get on PSI, but I'd also get at least one more connection because
it's common sense to get multi-homed these days.
Joe Backhoe Operator is out to get you.
