Buying IP Bandwidth Across a Peering Exchange

The exchange in question is Equinix. Their sales team is leading me
to believe there are multiple exchange products. One where you can peer
with providers (Google, Netflix for example) and then one where you can
create virtual private layer 2 vlans between providers. Then there is also
the traditional cross connect fee of $350 if you want to go from one
cage/rack to the other.

So in a situation where we are getting a 10Gig transport wave to Equinix,
we would ideally like to split this wave's use to 5Gbps of traffic going to
the peering exchange for traffic going directly to Google, Netflix, and
other CDN's, and then 5Gbps of pure IP transit going to a low cost provider
like HE.net. Of course providers like HE.NET are also peers on the peering
exchange, so it seems possible that we could just opening a peering
conenction with them.

I think the way most providers would do this would be to get a rack and
power with Equinix. Pay a cross connect fee from the wave provider to our
rack. Pay for an exchange port (which includes a cross connect to the
exchange) for the 5GBPS of traffic going to Netflix, Google, etc. And then
pay for yet another cross connect going to HE.net's cage to get pure IP
from them.

If I can buy transit directly I avoid the expenses of having to pay for
space, power, another router/switch, plus a second cross connect. Thats
quite a bit of money saved.

Are exchanges really that unreliable compared to a traditional cross
connect?
