There aren't many cheap webhosts that support Pylons. Generally they
are geared toward PHP and aren't interested in hearing about the
particular needs of Python/Pylons. You can read the list archives to
see the occasional complaints.

One issue is memory. Pylons seems to use more memory than you'd
expect, so some people have outgrown the limited memory on their cheap
webhosts and been stuck with year-long contracts. For comparison, my
four apps just fit into 2 GB on startup, but I had to go up to 4GB
with heavy use to keep it from swapping excessively. Of course, it
depends what kind of database you have and whether you have sizeable
lookup tables in memory, etc. My apps currently have a resident size
of 60 MB, 24 MB, 87 MB, 38 MB, and 114 MB. The smallest is a
quasi-static side using Pylons just to log accesses to a db. (These
sizes are reported by 'ps'. Of course, there's a huge controversy over
how to calculate memory use on a shared-library system, and 'ps',
'top', and 'free' report significantly different numbers. I don't
understand the minutae of this, so I just believe whatever 'ps' or
'top' says.)

My sites run on our own servers. My second choice would be a virtual
server like linode, or perhaps a cloud server like Amazon EC2.
Rackspace has some Python programmers so they may have particular
Python support. And of course, there are a few Python-knowledgeable
webhosts around who at least know what Pylons is and can give you a
definitive answer on how much they support it, but I don't remember
their names. I like tummy.com because their network guy (Sean
Reifenschneider) volunteers to run the network at PyCon every year,
and that's a huge job.
