Metastock is certainly not the best..... but for drawing trendlines and technical studies its all you will possibly need, its only when you get into the deeper stuff that you need more expensive software, but metastock is very easy to use and has heaps of features.
You can use it offline to, its built for that.
P.S. This site may be of interest to you www.emule-project.net, just kinda install and search for metatock
