RE property analysis software

[Schelley Stamps]

Hello my fellow investors, Im wondering if I should invest in a RE property analysis software program? I went to a investor seminar where the guru's said they use "Propstream", which looks like a good site, but was wondering if anyone uses it themselves, and if so do you like it? Does it make research easier in areas around the US? Are there any other programs or software that any one who is a experienced investor likes better? There are a couple reviews online, but they're old, and the company responded that they had done some upgrades and fixes. Please be detailed in your response, Thank you in advance!
