Thanks for your responses, gentlemen. After further investigation, mendhak, you are right that one would be hard-pressed to find a host that has CR or even SSRS installed (or would be willing to install it) on a shared site. (Many will hosts install things for you if you move up to a virtual private server or a dedicated server, but then you must pay 4, 5, or more times the monthly rate compared to the shared plan - for example, $100 PER MONTH vs. $20 per month.)

So yes, plain old ASP.NET pages seemed like the way to go. As I have done many times in the past with classic ASP pages, if the client wants a report, my web app would create a csv file that they can download into Excel and away they go. This is not unreasonable.

However, I was still trolling around on the web searching for other reporting solutions - most of what I found were very expensive ($1000-2000 USD) and/or required server-side installation.

Then, I found something that might just do the trick (can generate XLS or PDF output, does not require server installation, and is very reasonable in cost: 125 EUR or about $177 USD). The website is here:

Seems like these guys have been around for a while, especially creating components for Borland/Dephi programmers. Anyone here ever use FlexCel?
