I'm looking into installing an aftermarket remote starter on my 03 Grand Cherokee, and am just wondering if anyone has any suggestions as to which brands are good, or specific models that are a good deal, but more importantly work well, and aren't a huge pain in the ass to install.

Bulldog seems to have some nice units, but I don't know much about them.

Well any system you have is going to involve cutting and splicing into the original wiring harness, so as long as you can do that, and do it well then you shouldn't have any problems. As far as brands, it would probably be best to check your local car audio/security shop and see what brands they recommend, as I'm not that good of a choice for asking about brands.
