You could actually build pretty decent services over GAE, while remaining within the free quota, if you can be efficient with resources. Billing rates are affordable too.
I am currently working on an ad-supported CRM (http://crm.ifreetools.com) and online application builder (http://creator.ifreetools.com) over Google App Engine. Both are multi-tenant apps and iFreeTools Creator is probably the only online app builder which enables building customizable apps online over Google App Engine.
The platform does have its restrictions, primarily to enable apps to scale well. If one can get comfortable with working within those restrictions, it gets easier.
