I use Teamviewer for personal matters but their free app has obvious limitations when it comes to commercial use (ie lack of branding, monthly connection time limit), and LogMeIn Rescue (www.logmein.com) is a bit too expensive as far as I'm concerned. The least costly one out there that I've come across is Techinline (www.techinline.com), and the only limitation I see right off the bat is absence of Mac support. Any other apps that anyone may be able to suggest?
