VSTS 2008 Load testing, Is it any good?

Question

I have already spent couple of weeks trying to use this tool to generate some webtest and load test. But every day it throws a weird problem for which I do not find anything in document.

examples:

1. Hidden variables (_lastfocus) not found in the context error.
2. Today, all of sudden it is now refusing to run some of the webtest which are part of the test mix in my load test run (is working fine with another load test).

Are enterprise level, expensive tools are only good? (like loadrunner, silkperformer etc).

Answer 1

It is great. Once you get your head around the terrible way that WebForms shuttle "html" between request and response I have found it to be great.
