ForkLift is a good software, but if you are looking for the cheaper alternative try CRAX (http://www.ewas.pl/crax/).
Yes! Forklift was the one thing I missed after switching to the Mac (besides of Quicken, of course) - bought PathFinder 1st since I didn't know anything about FL, but it is *way* to overloaded. FL is fast, reliable and I use it every day. I like it a lot (what I don't like is the name FL and this my 1st sony icon :-)
